Investigation of Hopanoid Biomarkers in Lake Sediments by GC-MS and RP-HPLC-APCI-MS

Blog Article

Hopanoids are mainly derived from bacteriohopanpolyols that occur especially in bacteria, show the importance of bacterial lipid contributions in geological materials.In this work, GC-MS and RP-HPLC-APCI-MS analyses of hopanoid biomarkers in oxic and Protection anoxic sediment samples from Lake Cadagno (Swiss Alps) and Lake Voua de la Motte (Haute Savoie, France) are presented Surface Cleaners/Sanitizers and discussed.Samples were ultrasonically extracted, fractionated by flush chromatography on silica gel and derivatised before the analyses.

Periodic acid/ sodium borohydride cleavage was used to identify highly functionalised hopanoids.
