An Introduction to Low-Pressure GC-MS (LPGC-MS)
Low-pressure GC-MS can speed up pesticide analysis threefold, providing important speed gains for busy food testing labs. Here, we share the background for this innovative technology, explaining how it works and why a new simplified setup makes it more accessible for routine analysis.
Featured Webinar—LPGC-MS: The Fastest Way for Pesticides Analysis
In this engaging, on-demand webinar, we explain how LPGC-MS gives pesticides analysis a significant speed boost. Installing a special pair of coupled columns allows the MS vacuum to lower the pressure in the GC column, which can result in run times three or more times faster than a conventional GC-MS column setup.
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.
Speed Up and Simplify Pesticides Analysis with In-Line Sample Preparation
This LC-MS/MS method for pesticide residue analysis in spinach was developed using automated in-line sample preparation (ILSP). The workflow using Revive ILSP cartridges was faster and simpler than traditional extraction and cleanup techniques, and the overall performance was comparable or better.
