At the beginning of 2023, our laboratory acquired a new gas chromatograph
coupled to tandem mass spectrometry (GC-MS/MS).
This state-of-the-art analysis is generally used for contaminants (pesticides,
...) and here enables us to improve our old phthalate analysis method with a
time saving, better sensitivity, increased selectivity and more
reliable quantification.
The phthalates analyzed are : Dimethyl phthalate (DMP), Diethyl phthalate (DEP),
Dipropyl phthalate (DPrP), Diisobutyl phthalate (DiBP), Dibutyl phthalate (DBP),
Benzylbutyl phthalate (BBP), Dicyclohexyl phthalate (DCHP), diethylhexyl phthalate
(DEHP), Dinoctyl phthalate (DnOP), Diethylhexyl terephthalate (DEHT), Diisononyl
phthalate (DiNP) and Diisodecyl phthalate (DiDP).
Phthalates, used as plasticizers to increase the flexibility, transparency and durability of plastics, can originate from the extraction and processing of vegetable oils. They can migrate from materials in contact with oil, such as pipes, storage tanks and packaging.

This method is therefore in line with food safety concerns, as phthalates are known to be endocrine disruptors.
