EURL Evaluation of New Hybrid Stationary Phase for Polar Pesticides in Food
In this paper published by MethodsX, a European Reference Lab (EURL) evaluates Raptor Polar X LC columns for the QuPPe method “Methanol extraction of polar pesticides without acidification.” Results are presented for sensitivity, linearity, and matrix effects in tomato, onion, quince, and orange.
A Methods-Based Guide to Laboratory Supplies for PFAS Testing
PFAS are ubiquitous in the environment and can even be found in laboratory equipment. Using high-quality lab supplies is essential for accurately monitoring these pervasive contaminants. This methods-based reference guide makes it easy to find the products you need for commonly used ASTM, DIN, EPA, and ISO methods.
Speed Up Multiresidue Pesticides Analysis in Food with Low-Pressure GC-MS
Low pressure GC-MS (LPGC-MS) provides significant speed gains using standard instrumentation. This LPGC-MS pesticides analysis provides a 3x speed advantage over conventional methods, eluting 209 compounds in ~8 min from strawberry extracts. A pre-assembled low-pressure column kit simplifies the setup.
How Long Are Pesticide Standards Good After the Ampul Is Opened?
It’s not uncommon for analysts to ask, "how long are reference standards stable after opening the ampul when stored and handled properly?" We designed an open ampul stability study using the pesticides in our LC and GC multiresidue kits to answer this question. Here’s what we found...
