ASTM D2549-02-Reapproved2012<\/h3>\n

Historical Standard: Standard Test Method for Separation of Representative Aromatics and Nonaromatics Fractions of High-Boiling Oils by Elution Chromatography<\/h4>\n
\n

ASTM D2549<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the separation and determination of representative aromatics and nonaromatics fractions from hydrocarbon mixtures that boil between 232 and 538\u00b0<\/span>C (450 and 1000\u00b0<\/span>F). Alternative procedures are provided for the separation of 2 g or 10 g of hydrocarbon mixture.<\/p>\n

Note<\/span> 1\u2014Some components may not be eluted from the chromatographic column for some types of samples under the conditions used in this method.<\/p>\n

Note<\/span> 2\u2014Test Method D2007 is an alternative method of separating high-boiling oils into polar compounds, aromatics, and saturates fractions.<\/p>\n

1.2 An alternative procedure is provided to handle samples boiling below 232\u00b0<\/span>C (450\u00b0<\/span>F), but whose 5 % point is above 178\u00b0<\/span>C (350\u00b0<\/span>F) as determined by Test Method D2887. This procedure is given in Appendix X1.<\/p>\n

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.<\/p>\n

1.4 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.<\/span><\/p>\n
