Speed Up Analysis of 3-MCPD and Glycidyl Esters in Edible Oils
Here we explore optimization strategies and present improved, indirect GC-MS and GC-MS/MS methods for 3-MCPD and glycidyl esters in edible oils. Using split injection and Pro EZGC software, analysis was up to 20 minutes faster per sample and produced improved peak shapes and resolution.
How Can You Make Food Homogenization Less of a Grind?
Sample homogenization plays a critical role in ensuring you get a representative sample and effective extraction, but it can be messy and time-consuming. This quick video shows how using dry ice makes sample homogenization, handling, and storage so much easier.
Direct Analysis of Glyphosate and 16 Other Polar Contaminants in Food
Direct analysis of underivatized glyphosate can be difficult due to too little retention on reversed-phase or HILIC columns and too much retention on anion-exchange columns. In this ASMS video poster, we present a novel hybrid ion-exchange/HILIC column and an LC-MS/MS method for glyphosate and 16 other polar contaminants in various food matrices.
Fast and Rugged Direct Analysis of Polar Pesticides in Spinach
This simple, direct LC-MS/MS analysis of polar pesticides in spinach provides good retention and peak shape over hundreds of injections. No time-consuming derivatization, ion-pairing steps, or long waits for column equilibration make this an advantageous workflow for fast-paced food labs.
