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.
LCGC International spoke to Akina Nara of Japan’s Tohoku Medical and Pharmaceutical University about a new study which links a blood compound to how long a body has been dead.
A method coupling gas chromatography-tandem mass spectrometry (GC-MS/MS) and multiple reaction monitoring (MRM) tracks lipid markers of decomposition in commingled remains.
This week's top stories on the Chromatography Online website spotlight LCGC International's new SFC-focused interview series charting the technique's rise alongside LC and GC, complemented by a practical GC data-reporting refresher and a study using chromatography to detect trace pesticides in tap water.
