Event Overview:
In recent years, product recalls and other scandals involving milk or infant formula in China, the US, and across the globe dramatically illustrate the economic and personal impact of food contamination and adulteration. With ever present demand worldwide for milk products that are free of adulterants, there has been a continued focus on regulation and the development of methods for testing milk and infant formula products. To support these activities, certified reference materials of the most commonly tested milk proteins and vitamins were developed for calibration and development of liquid chromatography–mass spectrometry (LC–MS)–based methods in infant formula testing. In this webinar, the product design, workflow and certification methods for milk protein or vitamin Certified Reference Materials (CRMs) will be presented, along with a discussion of the quality attributes of their certificates of analysis and analytical & stability challenges in their development.

Advances in Non-Targeted Analysis for PFAS in Environmental Matrices
March 27th 2025David Megson from Manchester Metropolitan University in Manchester, UK, spoke to LCGC International about the latest developments in non-targeted analysis (NTA) of per- and polyfluoroalkyl substances (PFAS) in environmental matrices based on a recent systematic review paper he has collaboratively published (1).
Study Explores Thin-Film Extraction of Biogenic Amines via HPLC-MS/MS
March 27th 2025Scientists from Tabriz University and the University of Tabriz explored cellulose acetate-UiO-66-COOH as an affordable coating sorbent for thin film extraction of biogenic amines from cheese and alcohol-free beverages using HPLC-MS/MS.
Multi-Step Preparative LC–MS Workflow for Peptide Purification
March 21st 2025This article introduces a multi-step preparative purification workflow for synthetic peptides using liquid chromatography–mass spectrometry (LC–MS). The process involves optimizing separation conditions, scaling-up, fractionating, and confirming purity and recovery, using a single LC–MS system. High purity and recovery rates for synthetic peptides such as parathormone (PTH) are achieved. The method allows efficient purification and accurate confirmation of peptide synthesis and is suitable for handling complex preparative purification tasks.
