Gas chromatography/electron impact mass spectrometry, fast atom bombardment mass spectrometry, mass-analyzed ion kinetic energy spectroscopy and B/E linked scan analysis of triaryl phosphates and triethylene glycol fatty acid esters.
Tris(isopropylphenyl/phenyl) phosphates and triethylene glycol dicaprate/caprylate mixtures of typical industrial compositions have been analyzed by fast atom bombardment (FAB) mass spectrometry, FAB collisional activation (CA) mass-analyzed ion kinetic energy spectroscopy and FAB/electron impact (EI) CA B/E linked scans. Data obtained by these state-of-the-art methodologies are compared qualitatively and semi-quantitatively with those provided by classical gas chromatography (GC)/EI MS. To identify the plasticizers in cases of suspected contamination, GC/EI MS still appears to be the method of choice whenever ultimate sensitivity and specificity are needed. In cases where these requirements are less demanding, FAB mass spectrometry and FAB tandem mass spectrometry may be sufficient and more convenient.
