Unmatched Robustness for Analysis of Per- and Poly-fluoroalkyl Substances in Difficult Food Matrices (Aug 2026)
Author(s)PerkinElmer, Inc.
In food safety testing, instrument reliability under real-world conditions is the true test of performance. This technical note showcases the durability and consistency of the PerkinElmer QSight® 500 LC/MS/MS system through an intensive robustness study, analyzing high-matrix food samples with minimal cleanup and no loss in sensitivity. Using a simplified QuEChERS extraction (no SPE), the system successfully analyzed PFAS analytes across complex matrices like salmon, avocado, pet food, and spices. The results highlight not only long-term stability but also the power of StayClean™ technology to reduce downtime and keep throughput high.
