PFAS LC Column Anatomy: Which Phase, Dimensions, and Particle Types Are Best?
PFAS analysis became much more challenging after PFOS and PFOA were banned in the EU and replaced with other PFAS products. This guide explores the impact of LC column phase, dimensions, and particle types and gives recommendations on which columns will perform best for different aspects of PFAS analysis.
An Introduction to Low-Pressure GC-MS (LPGC-MS)
In our last issue of the Restek Advantage, we demonstrated how low-pressure GC-MS can speed up pesticide analysis in food threefold. Today, we are sharing the background for this innovative technology and explaining how it works and why a new simplified setup makes it more accessible for routine analysis.
Automated In-Line Pigment Removal Increases Accuracy for Multiresidue Pesticide Analysis
Coextracted matrix components can suppress or enhance ionization, reducing the accuracy of quantitative LC-MS/MS data. In this video poster, we share a new Revive in-line sample preparation (ILSP) workflow that removes pigments and improves accuracy for 63 pesticides in spinach.
Neonicotinoid Insecticides and Honey Bee Health: What’s in Your Honey?
Many governments have limited or banned neonicotinoid insecticides due to potential toxicity to honey bees, whose role as pollinators is critical to global food production. Curious to see if neonicotinoids were in grocery store honey, we developed a QuEChERS and LC-MS/MS workflow, and here’s what we found…
