I need the cis and trans alcohol % from the attached information received by GC. The solvent was methanol. I believe this is done by using the peak area but I'm not sure about how to go about it.

Q. Preparation and properties of the diastereoisomers of 3,3,5-trimethylcyclohexanol
I need the cis and trans alcohol % from the attached information received by GC. The solvent was methanol. I believe this is done by using the peak area but I'm not sure about how to go about it.

A. Unfortunately I am unable to open .xlsx files at this moment (.xls files are ok), here is the guideline on how to determine cis-trans content from GC plot:

Chromatographic techniques separate mixtures of species based on their interactions with
a stationary phase (e.g. fused silica column) and a mobile phase (e.g. methanol). The column is usually derivatized to control its polarity (ranging from hydrophobic dimethylsiloxane to hydrophilic polyethylene glycol or any of a wide array of specialty coatings). The analyte molecules interact with the surface and exist ...

Solution Summary

Starting from the basic chromatographic concept, this solution offers clear and logical answer to the problem. Some references are also included for better understanding.
