However, when sampling needs to be performed repeatedly, at a defined depth or under controlled low-flow conditions, conventional manual sampling can become time-consuming and difficult to standardize.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>AML919 Groundwater Automatic Sampler<\/strong> is designed to provide a more controlled approach to groundwater sample collection. It integrates <strong>automatic sampling control, automatic sampling-depth adjustment and low-flow <a href=\"https:\/\/www.aimoli2016.cn\/\" title=\"\">groundwater sampling<\/a><\/strong> into one system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The system is designed for environmental professionals who need reliable groundwater samples while reducing repetitive manual operations during field monitoring.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What Is the AML919 Groundwater Automatic Sampler?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The AML919 is an automatic groundwater sampling system developed for groundwater monitoring and environmental sampling applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike a conventional manual groundwater sampler, AML919 is designed to automate important parts of the sampling process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its main functions include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Automatic groundwater sampling<\/li>\n\n\n\n<li>Low-flow groundwater sampling<\/li>\n\n\n\n<li>Automatic sampling-depth adjustment<\/li>\n\n\n\n<li>Periodic groundwater sampling<\/li>\n\n\n\n<li>Fixed-depth groundwater sampling<\/li>\n\n\n\n<li>Repeated groundwater monitoring<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The system is particularly useful when the same monitoring well needs to be sampled repeatedly or when the sampling position needs to remain consistent despite changes in groundwater level.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Why Automatic Groundwater Sampling Is Important<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Traditional groundwater sampling usually requires field technicians to travel to the monitoring well, install the equipment, adjust the sampling position, perform the required sampling operation and collect the samples manually.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This approach can work well for small projects.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, the workload increases significantly when a monitoring program involves:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Multiple monitoring wells<\/li>\n\n\n\n<li>Repeated sampling<\/li>\n\n\n\n<li>Long-term groundwater monitoring<\/li>\n\n\n\n<li>Different sampling depths<\/li>\n\n\n\n<li>Periodic sampling schedules<\/li>\n\n\n\n<li>Remote monitoring locations<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In these situations, automation can reduce repetitive field operations and improve consistency between sampling events.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The purpose of AML919 is therefore not simply to replace a manual sampler. It is designed to make <strong>repeated groundwater sampling more controlled and easier to manage<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Three Common Challenges in Groundwater Sampling<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">1. Repeated Manual Sampling Requires Significant Field Work<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Long-term groundwater monitoring may require the same monitoring wells to be sampled repeatedly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Every sampling event can involve:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Traveling to the monitoring site<\/li>\n\n\n\n<li>Preparing sampling equipment<\/li>\n\n\n\n<li>Checking the groundwater level<\/li>\n\n\n\n<li>Positioning the sampler<\/li>\n\n\n\n<li>Collecting the groundwater sample<\/li>\n\n\n\n<li>Handling and transporting the sample<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">When the number of wells increases, these repeated operations can consume considerable time and labor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 uses automatic sampling control to reduce the amount of manual intervention required during the sampling process.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">2. Groundwater Levels Can Change<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater levels are not always constant.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They can change because of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Seasonal variations<\/li>\n\n\n\n<li>Rainfall<\/li>\n\n\n\n<li>Groundwater recharge<\/li>\n\n\n\n<li>Pumping activities<\/li>\n\n\n\n<li>Industrial water consumption<\/li>\n\n\n\n<li>Natural hydrogeological changes<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If the groundwater level changes but the sampling position remains unchanged, the actual sampling conditions may differ between monitoring events.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 addresses this problem through its <strong>automatic sampling-depth adjustment function<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The system can adjust the sampling position according to groundwater-level changes, helping maintain the required sampling depth during different monitoring periods.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">3. Manual Operation Can Affect Sampling Consistency<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Groundwater sampling involves several variables that may change from one sampling event to another.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sampling position<\/li>\n\n\n\n<li>Pumping conditions<\/li>\n\n\n\n<li>Sampling time<\/li>\n\n\n\n<li>Operator technique<\/li>\n\n\n\n<li>Sampling frequency<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When sampling is performed manually over a long period, these variables can introduce differences between individual sampling events.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Automatic control helps reduce some of these variations and provides a more repeatable sampling workflow.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">AML919 Automatic Groundwater Sampling Solution<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 combines three core functions:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Automatic Sampling Control<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The system can perform groundwater sampling according to preset operating requirements, reducing the need for continuous manual operation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Low-Flow Sampling<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 supports low-flow groundwater sampling, helping reduce unnecessary disturbance to the groundwater during sample collection.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Automatic Depth Adjustment<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The sampling position can be adjusted according to groundwater-level changes, helping maintain a consistent sampling depth.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Together, these functions provide a controlled approach to groundwater sample collection.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">How AML919 Works<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The basic working process can be understood as:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Monitoring Well<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2193<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Groundwater-Level Monitoring<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2193<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Automatic Sampling-Depth Adjustment<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2193<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Controlled Low-Flow Sampling<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2193<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Automatic Sample Collection<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2193<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Sample Preservation and Laboratory Analysis<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This workflow is particularly suitable for groundwater monitoring projects where sampling conditions need to remain as consistent as possible.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Automatic Groundwater Sampling<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The automatic sampling function is one of the main differences between AML919 and conventional manual sampling equipment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once the system has been configured according to the project requirements, automatic control can reduce the need for technicians to repeatedly adjust the sampling equipment during field operations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is particularly useful for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Periodic monitoring<\/li>\n\n\n\n<li>Long-term monitoring<\/li>\n\n\n\n<li>Multiple monitoring wells<\/li>\n\n\n\n<li>Repeated groundwater sampling<\/li>\n\n\n\n<li>Projects requiring consistent sampling procedures<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For large groundwater monitoring programs, reducing repetitive manual operations can significantly simplify field management.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Low-Flow Groundwater Sampling<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 supports <strong>low-flow groundwater sampling<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Low-flow sampling is intended to collect groundwater while minimizing unnecessary disturbance to the monitoring well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Excessive pumping or disturbance can affect groundwater conditions and may increase turbidity or cause unnecessary mixing within the well.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A controlled low-flow approach can therefore be useful when the objective is to obtain a representative groundwater sample while maintaining relatively stable sampling conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The appropriate pumping rate and sampling procedure should be determined according to the monitoring-well conditions and applicable environmental sampling requirements.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Automatic Sampling-Depth Adjustment<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">One of the key features of AML919 is its automatic sampling-depth adjustment capability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The groundwater level in a monitoring well can change over time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the project requires sampling from a specific groundwater position, simply installing the sampler at one fixed physical position may not always provide the same relative sampling condition.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 can adjust the sampling depth according to groundwater-level changes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This makes it suitable for projects requiring:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fixed-depth groundwater sampling<\/li>\n\n\n\n<li>Repeated sampling from the same groundwater position<\/li>\n\n\n\n<li>Long-term monitoring<\/li>\n\n\n\n<li>Periodic groundwater quality assessment<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Fixed-Depth Groundwater Sampling<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Fixed-depth sampling can be important when monitoring groundwater over an extended period.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, an environmental monitoring project may require samples to be collected from approximately the same groundwater layer every month.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the groundwater level changes, the sampling equipment may need to be repositioned.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AML919&#8217;s automatic depth adjustment function is designed to address this requirement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instead of relying entirely on manual adjustment, the system can automatically respond to groundwater-level changes and maintain the required sampling position.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">AML919 for Long-Term Groundwater Monitoring<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 is particularly suitable for long-term groundwater monitoring programs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Long-term monitoring often involves repeated sampling from the same wells over months or years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The objective is not only to collect samples, but also to make the sampling process as consistent as practical.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 can help standardize:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sampling depth<\/li>\n\n\n\n<li>Sampling method<\/li>\n\n\n\n<li>Sampling operation<\/li>\n\n\n\n<li>Sampling frequency<\/li>\n\n\n\n<li>Field operation<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This makes the system suitable for environmental monitoring programs where repeated groundwater sampling is required.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">AML919 for VOC Groundwater Sampling<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 can also be used in groundwater sampling applications involving <strong>volatile organic compounds (VOCs)<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">VOC sampling requires careful control because unnecessary disturbance and exposure to air can affect sample integrity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Low-flow sampling can help reduce unnecessary disturbance during groundwater collection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, obtaining reliable VOC samples requires a complete sampling procedure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to the equipment, operators should pay attention to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Purging procedures<\/li>\n\n\n\n<li>Flow rate<\/li>\n\n\n\n<li>Sample transfer<\/li>\n\n\n\n<li>Sample containers<\/li>\n\n\n\n<li>Headspace<\/li>\n\n\n\n<li>Preservation<\/li>\n\n\n\n<li>Transportation<\/li>\n\n\n\n<li>Laboratory requirements<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 should therefore be used together with the appropriate VOC sampling and preservation procedures.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Applications of AML919<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">The AML919 Groundwater Automatic Sampler can be used in a range of groundwater monitoring applications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Environmental Groundwater Monitoring<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For routine groundwater quality and environmental monitoring programs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Hydrogeological Investigation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For groundwater investigation projects requiring controlled sampling at defined depths.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Groundwater Quality Assessment<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For collecting groundwater samples for laboratory testing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Long-Term Groundwater Observation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For repeated sampling from the same monitoring wells over an extended period.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Groundwater Pollution Investigation<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For groundwater sample collection during environmental contamination investigations.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">VOC Groundwater Sampling<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For applications requiring controlled low-flow groundwater sample collection.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Multi-Well Monitoring<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For projects involving repeated sampling across multiple monitoring wells.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">What Parameters Can AML919 Monitor?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">It is important to distinguish between <strong>groundwater sampling<\/strong> and <strong>groundwater quality measurement<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 is primarily designed for groundwater sample collection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It can work together with groundwater multiparameter monitoring instruments when field water-quality measurements are required.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on the selected monitoring instrument, groundwater parameters may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Temperature<\/li>\n\n\n\n<li>pH<\/li>\n\n\n\n<li>Electrical conductivity<\/li>\n\n\n\n<li>Dissolved oxygen<\/li>\n\n\n\n<li>Turbidity<\/li>\n\n\n\n<li>ORP<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The functions can therefore be divided into three stages:<\/p>\n\n\n\n<p

class=\"wp-block-heading\">Who Should Consider AML919?<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 can be particularly useful for organizations that conduct repeated groundwater sampling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Potential users include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Environmental monitoring companies<\/li>\n\n\n\n<li>Environmental

sampler?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A groundwater automatic sampler is equipment designed to collect groundwater samples automatically according to defined sampling conditions or schedules. It can reduce manual field operations and improve the consistency of repeated groundwater monitoring.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What sampling method does AML919 use?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 supports low-flow groundwater sampling methods designed to reduce unnecessary disturbance during sample collection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can AML919 perform fixed-depth groundwater sampling?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. AML919 supports automatic sampling-depth adjustment, allowing the sampling position to be maintained according to groundwater-level changes and project requirements.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Can AML919 be used for VOC groundwater sampling?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. AML919 can be used for VOC groundwater sampling applications where controlled low-flow sample collection is required. The complete sampling, preservation and transportation procedure should follow the applicable VOC sampling requirements.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Does AML919 measure groundwater quality parameters?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 is primarily a groundwater sampling system. For groundwater quality measurement, it can work together with multiparameter water-quality instruments that measure parameters such as temperature, pH, conductivity, dissolved oxygen, turbidity and ORP.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What types of projects can use AML919?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">AML919 can be used for environmental groundwater monitoring, hydrogeological investigation, groundwater quality assessment, long-term groundwater observation, groundwater pollution investigation and repeated field sampling programs.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"576\" height=\"1024\" src=\"http:\/\/www.aimoli2016.cn\/wp-content\/uploads\/2026\/06\/ChatGPT-Image-2026\u5e746\u670824\u65e5-22_16_25-576x1024.png\" alt=\"\" class=\"wp-image-185\" srcset=\"https:\/\/www.aimoli2016.cn\/wp-content\/uploads\/2026\/06\/ChatGPT-Image-2026\u5e746\u670824\u65e5-22_16_25-576x1024.png 576w, https:\/\/www.aimoli2016.cn\/wp-content\/uploads\/2026\/06\/ChatGPT-Image-2026\u5e746\u670824\u65e5-22_16_25-169x300.png 169w, https:\/\/www.aimoli2016.cn\/wp-content\/uploads\/2026\/06\/ChatGPT-Image-2026\u5e746\u670824\u65e5-22_16_25-768x1365.png 768w, https:\/\/www.aimoli2016.cn\/wp-content\/uploads\/2026\/06\/ChatGPT-Image-2026\u5e746\u670824\u65e5-22_16_25-864x1536.png 864w, https:\/\/www.aimoli2016.cn\/wp-content\/uploads\/2026\/06\/ChatGPT-Image-2026\u5e746\u670824\u65e5-22_16_25.png 941w\" sizes=\"auto, (max-width: 576px) 100vw, 576px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Groundwater sampling is an essential part of environmental monitoring, hydrogeological investigation and groundwater quality assessment.
