Analysis of Complex Phthalate Mixtures by GC–TOF MS with Select‑Ev Soft Ionization
25 Feb 2019This study shows how the acquisition of ‘soft’ electron ionisation spectra offers significant advantages for the GC–MS analysis of phthalates. In particular, it has been shown that the increased intensity of high-m/z ions allows discrimination between symmetrically-substituted phthalates and those with two different alkyl chains, for improved understanding of the constitution of complex phthalate mixtures used in consumer goods and industrial products.

GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis.
