Development and Evaluation of a 66-Well Plate Using a Porous Sorbent in a Four-Phase Extraction Assisted by Electric Field Approach

Abstract

, inter- (3 consecutive days) and intraday precision determined for 4 concentration levels ( n = 6, each) were lower than 29% and mean recoveries for these concentrations ranging from 95% to 115%. The results demonstrated that the 66-well plate provides a stable, reproducible, and simple way to conduct extractions of ionic compounds from complex aqueous matrixes. The effectiveness of the low-cost cellulose cone tips used as a solid fourth phase also confirmed that it can easily overcome many drawbacks of similar liquid-liquid-liquid approaches.
