This unusual hopane-like compound is recognised together with the hopanes in the m/z 191 mass chromatogram and was for many years used as a biomarker of hypersalinity due to its common high abundance in sediments deposited under such conditions.  However, a key paper by Sinninghe-Damsté et al.

IGI’s software has a powerful equation system that computes derived values automatically when input properties are provided. But what are input properties and whare derived values? Â
Let’s take everyone’s favourite pristane/phytane ratio as an example.

Apologies for beginning this note with some history… When I worked on my Ph. D. project in the mid-1980s I witnessed the arrival of the first desk-top computers into our laboratory in Bristol.  They were expensive and clunky, and we only had a few.
