LCGC Europe Application Note Alert Having trouble viewing this email? Click here HPLC Generic HPLC-ELSD Applications for Food Analysis To show the strength and the versatility of this ELSD model, several LC methods applicable to food analysis are presented in this application note. Revealing Impurities Concealed by API Peak This application note shows how 2D-LC can separate and quantify two compounds with similar structures and retention behaviour but with widely different concentrations.   GPC Determination of Copolymer Composition and Molar Mass Copolymers cannot be characterized by standard GPC. The addition of MALS, UV, and RI detectors provides accurate distributions of molar mass and copolymer fractions.   Sample Prep Removal of Purple Pigmentation from Cannabis Using QuEChERS This application note outlines a QuEChERS extraction procedure for the analysis of 5 mycotoxins and 47 pesticides in cannabis.
