The AML919 Groundwater Sampling System<\/strong> is a professional groundwater sampling and well-purging system designed for groundwater monitoring, environmental investigation and groundwater quality sampling<\/strong>, with particular suitability for VOC groundwater sampling<\/strong>.<\/p>\n\n\n\n

AML919 integrates groundwater well flushing, sample collection and field monitoring into a practical sampling system. Its design focuses on improving sampling efficiency while reducing the risk of volatilization loss and cross-interference during the sampling process.<\/p>\n\n\n\n

The system is developed and manufactured by AIMOLI Environmental Instruments<\/strong> in China and is designed for professional environmental monitoring applications.<\/p>\n\n\n\n

1. Main Applications<\/h2>\n\n\n\n

AML919 is designed for groundwater monitoring wells and environmental sampling projects where representative groundwater samples are required.<\/p>\n\n\n\n

Typical applications include:<\/p>\n\n\n\n

    \n
  • Groundwater monitoring<\/li>\n\n\n\n
  • Groundwater well flushing<\/li>\n\n\n\n
  • Groundwater sample collection<\/li>\n\n\n\n
  • VOC groundwater sampling<\/li>\n\n\n\n
  • Environmental site investigation<\/li>\n\n\n\n
  • Groundwater quality assessment<\/li>\n\n\n\n
  • Contaminated-site investigation<\/li>\n\n\n\n
  • Groundwater monitoring programs<\/li>\n\n\n\n
  • Environmental laboratory sampling<\/li>\n<\/ul>\n\n\n\n

    The system can be used for both routine groundwater sampling and projects that require higher sampling efficiency and controlled sampling procedures.<\/p>\n\n\n\n

    2. Groundwater Well Flushing and Sampling in One System<\/h2>\n\n\n\n

    AML919 is designed to support two important stages of groundwater monitoring:<\/p>\n\n\n\n

    Well flushing \/ purging<\/strong><\/p>\n\n\n\n

    \u2193<\/p>\n\n\n\n

    Groundwater sample collection<\/strong><\/p>\n\n\n\n

    This integrated approach allows field technicians to prepare the monitoring well and collect groundwater samples using the same sampling system.<\/p>\n\n\n\n

    The system is particularly useful for environmental teams that need to visit multiple monitoring wells during a single working day.<\/p>\n\n\n\n

    3. Designed for VOC Groundwater Sampling<\/h2>\n\n\n\n

    One of the main application areas of AML919 is VOC groundwater sampling<\/strong>.<\/p>\n\n\n\n

    Volatile organic compounds can be affected by sampling conditions because excessive agitation, exposure to air or inappropriate handling may influence sample integrity.<\/p>\n\n\n\n

    AML919 is designed to reduce unnecessary exposure and disturbance during the sampling process.<\/p>\n\n\n\n

    When used together with appropriate sampling procedures, containers and preservation methods, the system can help reduce the risk of volatilization loss and cross-interference during groundwater sample collection.<\/p>\n\n\n\n

    For regulated environmental projects, the complete sampling procedure should always follow the applicable local or national sampling standard.<\/p>\n\n\n\n

    4. Rapid Groundwater Sampling<\/h2>\n\n\n\n

    A key feature of AML919 is its rapid water-output capability.<\/p>\n\n\n\n

    The system can achieve approximately 3 minutes of water output<\/strong> under suitable operating conditions.<\/p>\n\n\n\n

    This allows environmental sampling teams to improve field efficiency and potentially complete more monitoring wells within a working day.<\/p>\n\n\n\n

    For projects involving multiple groundwater monitoring wells, improved sampling efficiency can reduce field time and transportation costs.<\/p>\n\n\n\n

    Actual sampling time depends on well depth, groundwater conditions, pumping configuration and field procedures.<\/p>\n\n\n\n

    5. High Sampling Efficiency for Multi-Well Projects<\/h2>\n\n\n\n

    AML919 is designed for projects where multiple groundwater monitoring wells need to be sampled.<\/p>\n\n\n\n

    Under suitable field conditions, users can sample approximately 2\u20133 wells per day<\/strong>, depending on well depth, site conditions, required sampling procedures and the time required for each monitoring location.<\/p>\n\n\n\n

    This makes AML919 particularly suitable for:<\/p>\n\n\n\n

      \n
    • Large groundwater monitoring programs<\/li>\n\n\n\n
    • Environmental investigation projects<\/li>\n\n\n\n
    • Industrial site monitoring<\/li>\n\n\n\n
    • Contaminated-site investigations<\/li>\n\n\n\n
    • Routine monitoring of multiple wells<\/li>\n<\/ul>\n\n\n\n

      The actual number of wells that can be completed in one day depends on the specific project conditions.<\/p>\n\n\n\n

      6. Reduced Volatilization and Cross-Interference Risk<\/h2>\n\n\n\n

      Groundwater sampling quality is influenced not only by the sampling equipment but also by the complete sampling procedure.<\/p>\n\n\n\n

      AML919 is designed to minimize unnecessary disturbance during groundwater sampling and reduce the risk of volatilization loss and cross-interference.<\/p>\n\n\n\n

      This feature is particularly important when collecting samples for VOC analysis.<\/p>\n\n\n\n

      The system should be operated according to the applicable sampling protocol, and appropriate cleaning, decontamination, sample preservation and container procedures should be followed between sampling locations.<\/p>\n\n\n\n

      7. Sampling Depth<\/h2>\n\n\n\n

      AML919 has a standard sampling depth of approximately 70 meters<\/strong>.<\/p>\n\n\n\n

      The system has also been used in field applications at depths of approximately 300 meters<\/strong>.<\/p>\n\n\n\n

      Deep-well applications depend on the actual well structure, water level, cable configuration, power supply and sampling requirements.<\/p>\n\n\n\n

      For wells deeper than the standard operating range, customers should provide detailed project information so that AIMOLI can confirm the appropriate configuration.<\/p>\n\n\n\n

      8. Suitable for Different Well Diameters<\/h2>\n\n\n\n

      AML919 is designed for groundwater monitoring wells with different configurations.<\/p>\n\n\n\n

      Before selecting the system, users should provide:<\/p>\n\n\n\n

        \n
      • Well diameter<\/li>\n\n\n\n
      • Well depth<\/li>\n\n\n\n
      • Water level<\/li>\n\n\n\n
      • Required sampling depth<\/li>\n\n\n\n

          15. Important Operating Considerations<\/h2>\n\n\n\n

          Groundwater sampling results depend on more than the sampling equipment alone.<\/p>\n\n\n\n

          For reliable sampling, operators should also consider:<\/p>\n\n\n\n

            \n
          • Well construction<\/li>\n\n\n\n
          • Groundwater level<\/li>\n\n\n\n
          • Sampling depth<\/li>\n\n\n\n
          • Purging procedure<\/li>\n\n\n\n
          • Flow rate<\/li>\n\n\n\n
          • Sample container<\/li>\n\n\n\n
          • Decontamination procedure<\/li>\n\n\n\n
          • Sample preservation<\/li>\n\n\n\n
          • Transportation conditions<\/li>\n\n\n\n
          • Applicable environmental standards<\/li>\n<\/ul>\n\n\n\n

            For VOC sampling, minimizing exposure to air and unnecessary agitation is particularly important.<\/p>\n\n\n\n

            AML919 should therefore be used as part of a complete sampling procedure rather than considered as a standalone guarantee of sample quality.<\/p>\n\n\n\n
