Novel Methods Using Mass Spectrometry for Food Safety—From Contamination to Nutrition
In the human food supply, public confidence is affected by contaminants and misreporting of nutritional information. This article highlights three events that required development of new mass spectrometry methods, including the detection of pesticides (such as fipronil and glyphosate), and the detection and quantification of fat-soluble vitamins.
Comprehensive Identification of Migrating Compounds from Plastic Food Packaging Materials Using LC–HRAMS
This study assesses whether two commonly used plastic packaging materials are safe for use using liquid chromatography (LC) with high-resolution acccurate mass spectrometry (HRAMS) and data‑independent acquisition (DIA).
A Robust and Sensitive Method for Detecting Glyphosate and Other Polar Pesticides in Food and Water: Multiple Analytes in a Single Injection without Derivatization
A new high-throughput LC–MS/MS method meets the challenge of eliminating matrix effects for monitoring, with high specificity, polar organic pesticides such as glyphosate in food and water, while meeting targeted limits of detection.
Comprehensive Identification of Migrating Compounds from Plastic Food Packaging Materials Using High-Resolution Mass Spectrometry
This study assesses whether two commonly used plastic packaging materials are safe for use. Their potential migrants are analyzed using data-independent acquisition and liquid chromatography coupled with high-resolution, accurate-mass mass spectrometry.
Novel Methods Using Mass Spectrometry for Food Safety—From Contamination to Nutrition
This article highlights three events that require new method development to meet various detection needs, ranging from the detection of pesticides such as fipronil and glyphosate, to the detection and quantification of fat-soluble vitamins.
