Technical Field

[0002] Before the analysis and testing of water environment samples, it is necessary to process the samples. Representative, uniform, and appropriately sized samples should be processed to different degrees to ensure that the recovery rate of the components to be tested is high, the interference is small, the detection concentration range is optimal, and the cost is the lowest. In addition, the samples should be compatible with the analytical method to ensure that the analytical data is valid and accurate. In the analysis and testing of water environment samples, due to the complex composition of the samples and the many interfering factors, when the content of the analyte is below the detection limit of the analytical method, the components to be tested must be separated and enriched.

[0003] In the prior art, when separating and enriching the components to be tested, a filter layer is used to intercept suspended solids and other impurities in the water sample. Due to the selective permeability of the filter layer, the separation process is slow, and the various liquid components in the mixed liquid are different, which are easily carried out during separation, resulting in the need for secondary separation. Therefore, we propose a water sample rapid separation and processing device to solve the above problems. Utility Model Content
