Fig. 6. Mass spectrum of lanosterol from Gemmata obscuriglobus. Shown is the trimethylsilyl derivative, obtained at 70 eV (1 eV = 1.602 ´10–19 J) on an Agilent Technologies 6890 gas chromatograph (GC) system with a programmable temperature vaporization (PTV) inlet, using a CPSil-5 column and interfaced to an Agilent Technologies 5973 mass selective detector.
