23、pe This European Standard specifies a method for the determination of the boiling range distribution of petroleum products by capillary gas chromatography using flame ionisation detection. The standard is applicable to materials having a vapour pressure low enough to permit sampling at ambient tempe

24、rature, and which have a boiling range of at least 100 C. The standard is applicable to materials with initial boiling points (IBP) above 100 C and final boiling points (FBP) above 750 C, for example, heavy distillate fuels and residuals. The method is not applicable to bituminous samples. The test

25、method is not applicable for the analysis of petroleum or petroleum products containing low molecular weight components (for example naphthas, reformates, gasolines, diesel). Components containing hetero atoms (for example alcohols, ethers, acids, or esters) or residue are not to be analyzed by this

26、 test method. NOTE For the purposes of this European Standard, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction. WARNING The use of this European Standard may involve hazardous materials, operations and equipment. This European Standard d

27、oes not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. 2 Normative references The following re

The column temperature is raised a

38、t a linear reproducible rate and the area under the chromatogram is recorded throughout the analysis. Boiling points are assigned to the time-axis from a calibration curve, which is obtained by running a mixture of known normal alkanes covering the test portion boiling range, under the same conditio

39、ns. From these data, the boiling range distribution is obtained. The recovery at a specified temperature is determined by comparing the area under the chromatogram with that of a reference standard which has been completely eluted. The temperature at which the recovery was measured is recorded. NOTE

40、 If the found recovery is less than 100 %, the final boiling point is reported as 720 C or 750 C at that recovery. 5 Reagents and materials Unless otherwise stated, only chemicals of recognized analytical quality shall be used. 5.1 Liquid stationary phase, a methyl silicone stationary phase for the

41、column. 5.2 Carrier gases, helium, nitrogen or hydrogen, of at least 99,999 % (V/V) purity. Any oxygen present is removed by a chemical resin filter. Warning Follow the safety instructions from the filter supplier. 5.3 Hydrogen, grade suitable for flame ionisation detectors. 5.4 Compressed air, regu

42、lated for flame ionisation detectors. 5.5 Alkanes, normal alkanes of at least 98 % (m/m) purity from C5to C10, C12, C14, C16, C18, C20, C24and C28to be used with Polywax 655 or 1000 (5.6). NOTE The calibration mixture from ISO 3924 3 is also suitable. 5.6 Polywax 655 or 1000 5.7 Carbon disulfide, wi

43、th a minimum purity of 99,7 % (V/V). WARNING Extremely flammable and toxic.

45、easured. Dissolve 0,1 g of Polywax (5.6) in 7 ml carbon disulfide (5.7), warming gently if necessary. Prepare an equal volume mixture of alkanes (5.5) and add 10 l to the Polywax solution. NOTE 1 Commercially available alkane standards are suitable for column performance checks. NOTE 2 The calibrati

47、 (3.8) of the reference material with the total sample area of the unknown sample. Boiling Point Distribution Standard: to check the proper functioning of the system by comparing the results with a known boiling point distribution on a routine basis. Typical example is given in (5.9.2). 5.9.2 Refere

48、nce Material 5010, a reference sample that has been analyzed by laboratories participating in the test method cooperative study. Consensus values for the boiling range distribution of this sample are given in Table 1. 5.9.3 Cyclohexane. (C6H12)(99+ % pure) may be used in place of CS2for the preparat

49、ion of the calibration mixture. 5.9.4 Binary gravimetric blend, a binary distillate mixture with boiling points ranges that gives a baseline at the start, a baseline between the two peaks and an end time that is as close to the end of the chromatogram as possible (see Figure 3 and B.3). This mixture is used to check the relative response of the two distillates and to check the baselines at the start, middle and end of the chromatogram.
