STUDY OF MATRIX EFFECT IN PESTICIDE ANALYSIS BY GAS CHROMATOGRAPHY

In order to study the matrix-induced chromatographic response enhancement (matrix effect), we select three different types of biotic matrices (Lactuca sativa L., Physalis peruviana L. and Solanum tuberosum) and a group of pesticides of different physicochemical characteristics including organochlori...
