CNWSep polar pesticide specific column (quaternized polyvinyl alcohol anion analysis column)

Developed to solve various difficulties in the determination of residues of four pesticides and their metabolites, CNWSep polar pesticide specific columns were used. The four pesticides and their metabolites, including glyphosate, have suitable retention, good peak shape, stable peak emission, and no residue, and the chromatographic column has good durability and stability;
Applicable standards: GB 23200.122-2026 National Food Safety Standard Determination of Residues of Four Pesticides and Their Metabolites, including Glyphosate, in Plant derived Foods by Liquid Chromatography Mass Spectrometry;

CNWSepThe polar pesticide specific column is a newly developed product by Anpu Experimental, specifically designed for the detection of polar pesticides such as glyphosate, glufosinate ammonium, and their metabolitesA fixed chromatographic column can solve the problems of no retention, no peak, poor peak shape (tailing, wide peak), unstable peak time in polar pesticide determinationVarious difficulties such as residue.
