Food & Food Safety Analysis

Food & Food Safety

Food and feed analysis is a highly challenging task due to the different chemical nature and high number of analytes in complex samples. Food safety analysis follows strict governmental regulations for the control of maximum residue limits globally.

The PAL System as the industry standard front-end for GC/MS and LC/MS offers proven automated sample prep solutions. The PAL workflows for food and feed analysis follow the internationally published standard methods, often micromethods are applied for a safer green analytical chemistry.

Within the long list of monitored contaminants are pesticides using the QuECHERS extraction and micro-SPE (uSPE) cleanup for a wide range of food commodities. Also, the automated uSPE cleanup is applied for the analysis of veterinary drugs, residues of antibiotics and hormones. Highly polar pesticides like glyphosate and AMPA are analyzed using online-SPE technique on the PAL System.

For the analysis of volatile compounds like solvents or flavor compounds the PAL System offers tools for static and dynamic headspace analysis (ITEX DHS).

Solid Phase Microextraction technique (SPME ) with SPME Fibers or the rugged SPME Arrow are used for all areas in the food industry and quality control such as beverages, meat, oils, vegetables, wine, and food contact materials.

The PAL System provides fully automated sample preparation methods for the monitoring of processing contaminations in the vegetable oil industry, analysis for adulteration by blending, or the transfer of mineral oil hydrocarbons (MOSH, MOAH).

Other important applications include the characterization of fat content, composition, nutritional value, or cis/trans-isomerism. The PAL System offers automated extraction, saponification, derivatization and online GC injection in 24/7 operation.

The steadily growing demand for food and feed analysis calls for the PAL System to provide automated solutions for high sample throughput, reproducible and error free sample preparation.

PFAS in Cosmetics -A Comparative Analysis of Sample Preparation Techniques for PFAS Analysis

This application note explores a comparative study that tackles this challenge head-on by evaluating two powerful sample preparation techniques: Solid Phase Microextraction (SPME) and Micro Solid Phase Extraction (µSPE) for analyzing eight key PFAS in mascara by Liquid Chromatography with Mass Spectrometry (LC/MS). The investigation revealed that the two methods offer complementary strengths. SPME proved more sensitive for water-soluble PFAS and offered a simpler, filtration-free workflow. In contrast, automated µSPE excelled for oil-soluble PFAS but required a sample filtration step.
