Detection of Squalene and Squalane Origin with Flash Elemental Analyzer and Delta V Isotope Ratio Mass Spectrometer
Sylvie Guibert (1), Magali Batteau (1), Patrick Jame (1) and Thomas Kuhn (2)
The two source materials for squalene and squalane, shark liver oil and olive oil, exhibit significantly distinct carbon isotopic compositions (δ13C). This systematic difference in δ13C between the two sources can be employed to detect (a) the origin of squalane and (b) an adulteration of olive oil derived squalane by admixtures of shark liver oil derived squalane. Analysis of δ13C of squalene and squalane can be performed by means of an Elemental Analyzer coupled to an Isotope Ratio Mass Spectrometer (EA-IRMS).
