1.1 ,This test method covers the separation and determination of representative aromatics and nonaromatics fractions from hydrocarbon mixtures that boil between 232 ,°,C and 538 ,°,C (450 ,°,F and 1000 ,°,F). Alternative procedures are provided for the separation of 2 ,g or 10 ,g of hydrocarbon mixture.
Note 1: ,Some components may not be eluted from the chromatographic column for some types of samples under the conditions used in this method.
