2、ANDARDS BOARD (CGSB), under whose auspices this standard has been developed, is a government agency within Public Services and Procurement Canada. CGSB is engaged in the production of voluntary standards in a wide range of subject areas through the media of standards committees and the consensus pro

3、cess. The standards committees are composed of representatives of relevant interests including producers, consumers and other users, retailers, governments, educational institutions, technical, professional and trade societies, and research and testing organizations. Any given standard is developed

4、on the consensus of views expressed by such representatives.CGSB has been accredited by the Standards Council of Canada as a national standards-development organization. The standards that it develops and offers as National Standards of Canada conform to the criteria and procedures established for t

5、his purpose by the Standards Council of Canada. In addition to standards it publishes as National Standards of Canada, CGSB produces standards to meet particular needs, in response to requests from a variety of sources in both the public and private sectors. Both CGSB standards and CGSB national sta

6、ndards are developed in conformance with the policies described in the CGSB Policy and Procedures Manual for the Development and Maintenance of Standards.CGSB standards are subject to review and revision to ensure that they keep abreast of technological progress. CGSB will initiate the review of thi

7、s standard within five years of the date of publication. Suggestions for their improvement, which are always welcome, should be brought to the notice of the standards committees concerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards.An up-to-da

32、dure for the determination of paraffins, olefins, naphthenes, aromatics and unknowns (P.O.N.A.U.) in automotive gasolines using gas chromatography and flame ionization detection (GC/FID). Group types are determined by summing individual components. Individual hydrocarbon components greater than or e

33、qual to 0.01% by mass are determined. Oxygenated components including alcohols and ethers may be determined by this test method. See Annex A, Table A2 for example of retention times and response factors for oxygenates at concentrations typically found in automotive gasoline.This method applies to au

34、tomotive gasoline, ethanol-blended gasoline and denatured ethanol.Liquefied petroleum gas (LPG), naphtha, reformate, alkylate, blendstocks, and typical petroleum or petrochemical product may also be analyzed, however precision may not apply.The final boiling point of samples as defined by ASTM D86 s

35、hould not exceed 225C, however individual hydrocarbons eluting to nC15 can be determined.Components such as water which do not elute from the gas chromatograph or which have little or no response in a FID are not determined. The water content can be determined by using ASTM D6304, Procedure A.The se

36、paration of individual hydrocarbons and oxygenated compounds by the procedure described in this test method is not absolute and will result in some peaks that represent coeluting components (see Annex A, Table A2). Due to the possibility of coeluting peaks, the user is cautioned in the interpretatio

37、n of the data.Toluene and 2,3,3-trimethylpentane may coelute. If isooctane (2,2,4-trimethylpentane) and 2,3,4-trimethylpentane are present in the gasoline sample, it is probable that the sample contains 2,3,3-trimethylpentane. The concentration of 2,3,3-trimethylpentane is almost certain to be less

38、than the concentration of 2,3,4-trimethylpentane. When determining the concentration of toluene and 2,3,3-trimethylpentane, it is essential that the gas chromatographic integrator has individual peak processing capabilities including peak expansion and perpendicular drop. To detect 2,3,3-trimethylpe

39、ntane and toluene, it is essential for these components to be within a 5:1 ratio of each other with either component having the greater concentration. If these components are present in a greater than 5:1 ratio, the toluene and 2,3,3-trimethylpentane may appear as a coeluted peak, thus causing the c

40、omponent in the smallest concentration to be integrated with the more concentrated component.Typically forty components with concentrations greater than 1% by mass constitute an average of approximately 80% by mass of automotive gasoline. From these forty components, this method identifies coeluting

41、 peaks for toluene, 2-methylhexane, methylcyclopentane and n-hexane (see Annex A, Table A1). The forty components are identified in Table 5 by an asterisk beside its identification number.The number of coeluting peaks depends on the total number of individual components and the number of olefinic co

42、mponents present. The possibility of coeluting components increases with the increase of components detected after n-octane. Supplementary analytical techniques such as ASTM D1319 for olefins, D5580 and D5769 for aromatic components, D4815 and D5599 for oxygenates may assist in interpretation of dat
