Emery groundwater VOCs sampler

China is one of the 13 countries in the world with severe water shortage, and 92% of surface water has been polluted to varying degrees. Therefore, it is necessary to detect VOCs in groundwater, which is a major issue related to national economy and people's livelihood.

1) There are two companies in the United States that have this sampling device. With over 30 years of technological accumulation, it has become very mature.
2) At present, only national standards have been issued in China, and there is no second one besides Emery's successful research and development.
3) On the basis of the American sampler, we have iteratively updated this technology and are ready to participate in domestic bidding. The patent is also under review.
4) The American sampler has a depth of about 60 meters and requires multiple probes to be lowered into the well multiple times. However, Emery has successfully developed an integrated probe with a sampling depth of over 70 meters, which only requires a few pumping operations to complete well cleaning and sampling.
