Determining high-molecular-weight phthalates in sediments using GC-APCI-ToF-MS

abstract
The environmental analysis of phthalates is established and widespread with most classical methods based on gas chromatography mass spectrometry (GC-MS). Attention has recently turned to the analysis of di-isononylphthalate (DiNP) and di-isodecylphthalate (DiDP) but their analysis by GC results in an unresolved cluster of peaks that all predominantly fragment to the phthalic anhydride ion at m/z = 149. Consequently, quantification of DiNP and DiDP using the most abundant ion is impossible and the same sensitivity as for the single isomer phthalates cannot be reached. GC combined with atmospheric pressure chemical ionization (APCI) was used to analyse the high-molecular-weight phthalates. DiNP and DiDP were successfully ionized in proton transfer mode yielding spectra that contained the molecular ion as the base peak. The method was also applied to measure DiNP and DiDP in a sediment extract at relevant levels for environment samples.
