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.
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.
An Optimized QuEChERS Approach for Avocado
Avocado may be delicious, but it is difficult to deal with in the lab. High fat content and a lack of water mean adjustments must be made in order ensure accurate pesticide residue results. Here, we explore several QuEChERS extraction and cleanup options and present a recommended approach.
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.
