《用洗脱色谱法分离高沸点油典型芳烃和非芳烃馏分的试验方法》是石油,石油产品分类下的标准,The determination of compound types by mass spectrometry requires, in some instances, a preliminary separation of the petroleum sample into representative aromatics and nonaromatics fractions, as in Test Methods D 2425, D 2786, and D 3239. This test method provides a suitable separation technique for this application.1.1 This test method covers the separation and determination of representative aromatics and nonaromatics fractions from hydrocarbon mixtures that boil between 232 and 538176;C (450 and 1000176;F). Alternative procedures are provided for the separation of 2 g or 10 g of hydrocarbon mixture. Some components may not be eluted from the chromatographic column for some types of samples under the conditions used in this method.Note 1Test Method D 2007 is an alternative method of separating high-boiling oils into polar compounds, aromatics, and saturates fractions.<>1.2 An alternative procedure is provided to handle samples boiling below 232176;C (450176;F), but whose 5 % point is above 178176;C (350176;F) as determined by Test Method D 2887. This procedure is given in Appendix X1.1.3 The values stated in acceptable SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and heal practices and determine the applicability of regulatory limitations prior to use.其主要内容是洗脱,色谱法,馏分,芳烃。
