Application Notes: Food and Beverage

PFAS rules now reach the packaging itself. Under the EU Packaging and Packaging Waste Regulation, food contact packaging containing 25 ng/g or more of any individual PFAS cannot be placed on the market, so labs need targeted data at production volume. This application note shows a Direct Shoot LC-MS/MS method on the PerkinElmer QSight 500 system that quantifies 26 PFAS in food packaging bottles, pharmaceutical packaging bottles and packaged drinking water. It uses a simple methanol extraction and no SPE cleanup. Calibration runs from 0.05 to 25 ng/g, with recoveries predominantly within 70 to 130%.

The last AppNote in this Newsletter shows how liquid-liquid extraction of xylazine and medetomidine in plasma and urine can be fully automated and seamlessly combined with LC-MS/MS analysis. All critical steps - including extraction, mixing, centrifugation, evaporation, and solvent exchange - are performed by the MPS, enabling high-throughput workflows with excellent accuracy and precision at low concentration levels.

This AppNote highlights how salting-out assisted liquid-liquid extraction (SALLE) can be fully automated for the determination of bisphenol A (BPA) in beverages. The study demonstrates how automation removes sample-prep bottlenecks while ensuring consistent, robust results across a wide range of beverage matrices.

This AppNote demonstrates how liquid-liquid extraction for fatty acid methyl esters (FAMEs) in infant formula can be reliably automated in accordance with AOAC® 2012.13. Using the GERSTEL MPS, critical timing, mixing, and reagent addition steps are precisely controlled, ensuring reproducible and robust results.

This AppNote shows how manual liquid-liquid extraction can be directly translated into a fully automated workflow using the GERSTEL MPS. The result: highly reproducible data, reduced solvent exposure, and far less hands-on time for laboratory staff. Even complex steps such as mixing, evaporation, and reconstitution are handled reliably - making LLE more efficient and better suited for routine analysis.
