Where to find a hopanes and steranes free MS library?

15 October 2019 0 7K Report

I am interesting to find a free MS library of hopanes and steranes or any information related. Unfortunately our MS Varian software (Workstation 6.9.2) does not have an update one, just the demo version.

We already have the cromatograns and its spectrograns. Analysing the fragments 191 and 217, it is possible to verify the presence of hopanes and steranes respectively. However, we are not able to identify directly who is who. Hopanes and steranes were obtained from suspended sediments from a subtropical brazilian river.

We really appreciate any kind of help on this matter.

Thanks a lot.
