METHOD FOR DETERMINING CONTENT OF POLYCYCLIC AROMATIC HYDROCARBONS IN OIL-PLASTICIZERS Russian patent published in 2017 - IPC G01N30/14 

Abstract RU 2630854 C1

FIELD: chemistry.

SUBSTANCE: method for determining the content of polycyclic aromatic hydrocarbons in oil-plasticizers is to purify from interfering substances, and to concentrate the polycyclic aromatic hydrocarbons using column chromatography on silica gel, deactivated with water, using gradient elution, and then quantifying the content of polycyclic aromatic hydrocarbons in a purified sample by gas chromatography with mass-selective detection. The interfering components of the sample in the first stage of column chromatography are eluted with n-hexane, previously equilibrated with water.

EFFECT: expanding the list of analyzed polycyclic aromatic hydrocarbons to 23 individual and, in particular, to light polycyclic aromatic hydrocarbons in oil-plasticizers with high accuracy.
