Detection of Squalene and Squalane Origin with Flash Elemental Analyzer and Delta V Isotope Ratio Mass Spectrometer

[michelle-case]

Squalane (C30H62) is widely used in cosmetic products due to its high skin hydrating capability. Carbon isotope compositions (δ13C) of squalene and squalane from shark liver oil, olive oil, and mixtures of both oils were measured by a Thermo Scientific Flash 1112 EA for IRMS coupled to a Thermo Scientific Delta V Series IRMS via a Thermo Scientific ConFlo IV interface.
