The sad thing is...they are probably using a HPLC and just running the oil through their system.

The machines cost BIG MONEY and the buisness yeilds some serious payback (a lot of analysis done for drug companies). HPLC= High Pressure Liquid Choromotography. Basically they drop a bit of the sample into a special tube, run it, and they get a printout of what was in the stuff they tested.

We used to do this in high school chem (used the college's machine) to analyze the amount of caffeine in different beverages/foods.

My eventual career will probably end up working on such machines...love maintenence but car stuff is a hobby and is hard on the body/hands after too many years heh.

Anyone know someone hiring?
