Self-built Multi Channel Device Combination with Control Separately for Large Volume Liquid Concentration
This article analyzes the principles and characteristics of laboratory equipment currently used for liquid concentration,and proposes the use of commonly used laboratory instruments and apparatuses to build a multi-channel combination with individual control.This combination can conveniently expand sample flux and achieve individual control of sample operations.The combination was applied to the validation experiment of semi volatile organic pollutants in soil,as well as the process recovery experiments of dioxin and polychlorinated biphenyl isotope labeled internal standards,confirming that the combination device can achieve satisfactory experimental results.
