Simultaneous quantification of seven glycols in antifreeze liquids using direct liquid injection gas chromatography coupled with mass spectrometry

CONCLUSIONS: A method that requires only a two-step dilution of antifreeze samples combined with direct liquid injection GC-MS was validated for the simultaneous quantification of seven glycols (and their isomers) in 10 different types of antifreeze liquids. The results obtained in the validation procedure proved that the GC-MS method is sensitive and precise for the quantification of glycols.PMID:38212649 | DOI:10.1002/rcm.9686
