Gas Chromatography–Mass Spectrometry (GC-MS) plays a vital role in detecting restricted substances during RoHS compliance testing, especially for identifying brominated flame retardants and certain phthalates. I’d like to discuss how different labs calibrate and maintain GC-MS instruments for consistent accuracy, the challenges faced during complex matrix analysis, and any tips for optimizing detection limits in polymer samples.

Has anyone here implemented specific techniques or encountered difficulties in GC-MS analysis for RoHS testing?
