Description

technical field [0001] The invention relates to a test device for laboratory sample analysis, in particular to a test device for water removal and collection during sample analysis. Background technique [0002] Liquid-liquid extraction is often encountered in chemical analysis. The extracted organic reagent contains water, which affects the analysis and determination of the instrument, especially in the analysis of pesticides and fatty acids, which affects the gasification of drugs and brings errors to the analysis work. To remove the moisture in the organic solution to be analyzed, usually use a triangular funnel with absorbent cotton, place anhydrous sodium sulfate or other water-absorbing reagents on the absorbent cotton, and drop it by gravity, which is not only time-consuming, but also causes volatilization loss of volatile solvents. It causes changes in the concentration of the assay solution, and at the same time, the number of samples processed each time is also lim...
