Liquid Petroleum products. Determination of hydrocarbon types. Fluorescent indicator adsorption method

Alkalmazási terület

This International Standard specifies a fluorescent indicator adsorption method for the determination of hydrocarbon types over the concentration ranges from 5 % (VW) to 99 % (WV) aromatic hydrocarbons, 0,3 % (VW) to 55 % (V/V) olefins, and 1 % (VIV) to 95 % (V/v) saturated hydrocarbons in Petroleum fractions that distill below 315 “C. Restrittions inherent in the method and the determination of precision may limit its application as noted. NOTES 1 This method may apply to concentrations outside these ranges, but the precision has not been determined. 2 This test method is intended for use with full boiling range products. Cooperative data have established that the precision Statement does not apply to Petroleum fractions with narrow boiling ranges near the 315 “C limit. Such samples are not eluted properly, and results are erratic. 3 The applicability of this test method to products derived from fossil fuels other than Petroleum, such as coal, shale or tar Sands, has not been determined and the precision Statement does not apply to such products. 4 The precision of this test method has not been determined with oxygenated fuels and thus does not apply to automotive gasolines containing lead anti-knock mixtures. 5 The oxygenated blending components methanol, ethanol, methyl tert-butyl ether, tert-amyl methyl ether and ethyl tefi-butyl ether do not interface with the determination of hydrocarbon types at concentrations normally found in commercial Petroleum blends. These oxygenated compounds are not detected since they elute with the alcohol desorbent. Other oxygenated compounds must be individually verified. When samples containing oxygenated blending components are analyzed, the hydrocarbon type results tan be reported on an oxygenate-free basis or, when the oxygenate content is known, the results tan be corrected to a total-sample basis. 6 Samples containing dark-coloured components that interfere with reading the chromatographic bands cannot be analyzed.
