Liquid chromatography–tandem mass spectrometry (LC–MS/MS) measures galactose-1-phosphate in dried blood spots to monitor galactosemia.
PFAS testing requirements vary by matrix and analytical goal. See workflows spanning sample preparation, targeted LC-MS/MS analysis, combustion ion chromatography, high-resolution mass spectrometry and data processing for water, soil and other challenging samples. The guide also compares approaches for known PFAS quantitation and unknown screening.
