Field in-situ mud and water sample layering storage barrel

Abstract

The invention relates to a field in-situ mud and water sample layering storage barrel, and belongs to a storage device. The field in-situ mud and water sample layering storage barrel comprises a barrel body, wherein a mud and water separating filter screen is arranged in the barrel body, and is used for separating mud from water by virtue of rotation of a handle. According to the field in-situ mud and water sample layering storage barrel provided by the invention, a mud-water sample is thoroughly stored in a layering manner by using the filter screen so that the purpose of collecting an original sample is achieved, and the biological activity is lowered and the chemical reaction is reduced by using a condensed matter in an interlayer of the storage device.

Description

technical field [0001] The invention relates to a field in-situ mud and water sample layered storage barrel, which belongs to a storage device. Background technique [0002] In environmental monitoring, field collection is an essential work. When conducting field sampling work, it is often necessary to collect mud and water samples from the same location and bring them back to the laboratory for testing. However, since the mud-water sample is mixed and stored in the same container during transportation, some substances are easily exchanged at the mud-water sample interface, which affects the results of laboratory analysis. Or the traditional method, which separates the collected mud-water samples into two containers, but this method has too many samples, and the labels are unclear during the transportation process, which makes it impossible to analyze the numbers when they are confused. Moreover, at room temperature, there will be chemical reactions or microbial effec...

Problems solved by technology

However, since the mud-water sample is mixed and stored in the same container during transportation, some substances are easily exchanged at the mud-water sample interface, which affects the results of laboratory analysis.

Or the traditional method, which separates the collected mud-water samples into two containers, but this method has too many samples, and the labels are unclear during transportation, which makes it impossible to analyze the numbers when there is confusion

Moreover, at room temperature, there will be chemical reactions or microbial actions during the long transportation process, which will also lead to certain changes in the samples analyzed in the laboratory, which will affect the accuracy of laboratory data determination.

Storage buckets containing mud-water samples are heavy and require a lot of effort to move
