Significance and Use4.1 A knowledge of the hydrocarbon components compris-ing a petroleum naphtha, reformate, or alkylate is useful invaluation of crude oils, in alkylation and reforming processcontrol, in product quality assessment, and for regulator

41、ypurposes. Detailed hydrocarbon composition is also used asinput in the mathematical modeling of refinery processes.4.2 Separation of naphtha components by the proceduredescribed in this test method can result in some peaks thatrepresent coeluting compounds. This test method cannot attri-bute relati

42、ve concentrations to the coelutants. In the absence ofsupporting information, use of the results of this test methodfor purposes which require such attribution is not recom-mended.5. Interferences5.1 If present, olefinic hydrocarbons with boiling points lessthan 150 C will be separated and detected

43、along with thesaturates and aromatics. Some of the olefins will coelute withsaturates or aromatics and give erroneously high concentra-tions for those components. Some coelutions of PNA compo-nents above C7 may occur and results may not be completelyaccurate. Test Method D5443 may be used for carbon

44、 numberdistribution above C7 to verify results from this test method.5.2 Alcohols, ethers, and other organic compounds of simi-lar volatility can also interfere by coeluting with saturate oraromatic hydrocarbons thereby causing erroneously high val-ues to be determined.6. Apparatus6.1 Instrumentatio

45、nA gas chromatograph capable of col-umn oven temperature programming from 35 C to 200 C in1 Cmin increments is required. A heated flash vaporizinginjector designed to provide a linear sample split injection (forexample, 200:1) is also required for proper sample introduc-tion. The associated carrier

46、gas controls must be of adequateprecision to provide reproducible column flows and split ratiosin order to maintain analytical integrity. A hydrogen flameionization detector designed for optimum response with capil-lary columns (with the required gas controls and electronics)must meet or exceed the
