A Closed Sampling Solution for Groundwater Monitoring Wells The AML919 groundwater sampler features a 316 stainless steel pump body and corrosion-resistant PTFE sampling tubing. The entire sampling process is fully enclosed, effectively preventing cross-contamination of water samples. For groundwater VOCs sampling, the VOCs loss rate is less than 0.5%, with a recovery rate of up…

Three months ago, the technical manager, Mr. Zhu, of a nuclear power operation and management company in a city in southern China learned about AIMOLI through the internet and took the initiative to contact us. Mr. Zhu introduced that the company has more than 10 groundwater monitoring wells and needs to conduct regular groundwater sampling…

A Complete Solution from Sampling Equipment to Field Operations How to prevent cross-contamination in groundwater sampling? The key is not simply to “clean the sampler,” but to simultaneously control sampling equipment residues, contaminant transfer between different monitoring wells, volatilization loss during sampling, contamination caused by personnel operations, and sample preservation contamination. For groundwater environmental monitoring,…

1. Teacher Chen’s Challenge: River Microplastics Detection Has Become a Bottleneck in the Research Project A team led by Teacher Chen from the School of Environmental Science at a university in southern China is currently planning to apply for a research project on regional river management, in which river microplastics detection, continuous monitoring, and tracking…

Water Level Logging Instruments: How to Choose the Right Groundwater Monitoring Equipment Water Level Logging Instruments are essential for groundwater monitoring, well inspection, environmental testing, hydrogeological investigation, and groundwater sampling projects. However, choosing the right Water Level Logging Instruments is not simply about buying a device that can detect water. For professional groundwater monitoring, Water…

Groundwater VOC Sampling Deviation Reduced from 35% to 2%: A Well-Used Bladder Pump Saved a Project Traditional submersible pumps cause VOC volatilization and cross-contamination due to high-speed impeller disturbance, resulting in sampling deviations as high as 35% in 80-meter-deep wells. Two re-sampling attempts failed environmental protection department acceptance. After switching to the AML919 well-used bladder…

Measuring Groundwater Level: How to Choose a Ground Water Level Measuring Device Measuring groundwater level is a routine requirement for groundwater monitoring, environmental investigation, well inspection, groundwater sampling, and remediation projects. For contractors working with dozens or hundreds of monitoring wells, the biggest challenge is usually not understanding groundwater—it is completing measuring groundwater level work…

Bladder for Well Pump: How a Bladder Pump for Well Sampling Works A bladder for well pump is an important component in groundwater sampling equipment designed to collect groundwater while reducing disturbance to the sample. A bladder pump for well applications is particularly useful when groundwater samples must maintain good sample integrity, especially during VOC…

Low Flow Groundwater Sampling: Complete Guide to Low-Flow Groundwater Sampling and Equipment Low Flow Groundwater Sampling is a groundwater monitoring method designed to minimize well drawdown and disturbance during groundwater purging and sample collection. Compared with aggressive conventional pumping, low flow groundwater sampling focuses on maintaining stable hydraulic conditions around the well screen so that…

FTIR Analysis of Microplastics: How FTIR Is Used for Microplastic Identification FTIR analysis of microplastics is a widely used analytical approach for identifying the polymer composition of microplastic particles. By measuring the infrared absorption characteristics of a particle and comparing its spectrum with reference spectra, researchers can determine whether a microplastic is made from polymers…

How to Investigate Water Quality Anomalies in a 260-Meter Deep Well? AIMOLI AML921 Downhole Camera Identifies Three Key Issues In groundwater monitoring and deep well inspection projects, water quality anomalies in deep wells can be difficult to identify through conventional well cleaning and laboratory analysis alone. A groundwater monitoring station in northwest China recently faced…

How Can a Groundwater Water Level Meter Improve Monitoring Efficiency? An AML913 Case Study Wang, an engineer at a provincial environmental monitoring center, received his third rework notice from the laboratory—the groundwater water level data from three groups showed deviations of more than 5%, requiring the samples to be collected again! “Three people per team,…
