Analysis of 22-Component Group Type in Petroleum Fraction with INCOS Data System

A calculating program (using analogue data) with Finnigan INCOS DataSystem for 22-component group type analytical method is described. The22-CGT (aliphatic and one to seven-ring alicyclic hydrocarbons, ten aromatickydrocarbons and four aromatic sulfur types) which utilizes high resolutionmass spectrometry for analyzing 177-566°C boiling petroleum stock withoutrequiring aromatics and saturates separation, can be given.
