Belle,
Have you no access to GC? Look at column manufacturers websites for GC chromatograms.
Varian,Restek,Agilent etc.

MS from Menthol is an easy GLC application. I assume you meant Gas-Liquid Chromatography. From the oil I would have to look up application info from Agilent, Supelco, Restek, Alltech, etc

Waters has a nice site for HPLC applications.

Just look at the web hits and you will find lots of info, easy and free.

You can use a GCMS with a DB-wax or DB-FFAB 30 m 0.25 mm (for water sample) to analyse your oil.
