Technology principle
Sample is washed with carbon tetrachloride, then the total oil is measured by testing the organic layer. After the organic layer flows into a column filled with magnesium silicate to remove the animal and vegetable oils, the value of petroleum oil is displayed by testing the liquid. The animal vegetable oil is equal to the margin of the total oil and petroleum oil. The sample is tested at the wave number V2930cm-1(stretching vibration of C-H of CH2 group) V2960cm-1(stretching vibration of C-H ofCH3 group) andV3030cm-1(stretching vibration of C-H of aromatic ring).
