Reference Chromatograms for TPH

We are about to re-do our reference chromatograms for TPH analysis. This provides a source of chromatograms which clients can compare to their own results, and is especially useful if something unusual turns up.

It is easy for us to source normal petrol and diesel, or hardware supplies such as mineral turps. If anyone comes across a pure (hydrocarbon) product which they think would be useful to add to the mix, then please send us a few mL (1/4 of a VOC vial is heaps) along with as much detail as possible eg trade name, MSDS, etc. We are after the full range from solvents (Stoddards, White Spirits, printing, degreasing, etc), hydraulic and motor oils, etc.
Note that non-petroleum products such as limonene or pinenes/'natural' turpentine are also useful. 
Mark them "For reference TPH - See Peter/Ara".
We will put the updated document on our website as soon as we've done a reasonable number of new analyses.

If you have any comments or suggestions, please contact:
