| The mineral oil is extracted from the water sample, after acidification and adding of sodium chloride. The extract is anhydrated and concentrated. A part of the concentrated extract is injected into a gaschromatograph. The oil is detected by means of a flame ionisation detector (FID). The total peak area of C10 up to and including C40 alkanes is a measure for the quantity of mineral oil. |
