AI Technical Summary
Existing technologies for analyzing chemical contaminants in food samples suffer from problems such as insufficient matrix removal, time-consuming and labor-intensive sample preparation, incomplete matrix purification, and severe target loss. In particular, it is difficult to achieve efficient and rapid sample preparation and purification in complex food matrices.
An enhanced matrix removal (EMR) hybrid-mode permeation purification method is adopted, using EMR columns and blended adsorbents such as EMR-lipids, Carbon S, N-propylethylenediamine (PSA), and EC-C18 to remove the matrix through multiple interaction mechanisms, simplifying the sample preparation process and improving target recovery and purification efficiency.
It achieves efficient matrix removal from complex food matrices, improves target recovery rate, simplifies sample preparation process, reduces time and effort consumption, and reduces matrix effect and instrument contamination risk. It is suitable for high-throughput analysis of multiple types and residual pollutants.
