1、Designation: D 1319 08Designation: 156/97An American National StandardStandard Test Method forHydrocarbon Types in Liquid Petroleum Products byFluorescent Indicator Adsorption1This standard is issued under the fixed designation D 1319; the number immediately following the designation indicates the y
2、ear oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Depart
3、ment of Defense.1. Scope*1.1 This test method covers the determination of hydrocar-bon types over the concentration ranges from 5 to 99 volume %aromatics, 0.3 to 55 volume % olefins, and 1 to 95 volume %saturates in petroleum fractions that distill below 315C. Thistest method may apply to concentrat
4、ions outside these ranges,but the precision has not been determined. Samples containingdark-colored components that interfere in reading the chro-matographic bands cannot be analyzed.NOTE 1For the determination of olefins below 0.3 volume %, othertest methods are available, such as Test Method D 271
5、0.1.2 This test method is intended for use with full boilingrange products. Cooperative data have established that theprecision statement does not apply to narrow boiling petroleumfractions near the 315C limit. Such samples are not elutedproperly, and results are erratic.1.3 The applicability of thi
6、s test method to products derivedfrom fossil fuels other than petroleum, such as coal, shale, ortar sands, has not been determined, and the precision statementmay or may not apply to such products.1.4 This test method has two precision statements depictedin tables. The first table is applicable to u
7、nleaded fuels that donot contain oxygenated blending components. It may or maynot apply to automotive gasolines containing lead antiknockmixtures. The second table is applicable to oxygenate blended(for example, MTBE, ethanol) automotive spark ignition fuelsamples with a concentration range of 1340
8、volume percentaromatics, 433 volume percent olefins, and 4568 volumepercent saturates.1.5 The oxygenated blending components, methanol, etha-nol, methyl-tert-butylether (MTBE), tert-amylmethylether(TAME), and ethyl-tert-butylether (ETBE), do not interferewith the determination of hydrocarbon types a
9、t concentrationsnormally found in commercial blends. These oxygenatedcomponents are not detected since they elute with the alcoholdesorbent. Other oxygenated compounds shall be individuallyverified. When samples containing oxygenated blending com-ponents are analyzed, correct the results to a total-
10、sample basis.1.6 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.7 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to e

Summary of Test Method4.1 Approximately 0.75 mL of sample is introduced into aspecial glass adsorption column packed with activated silicagel. A small layer of the silica gel contains a mixture offluorescent dyes. W
20、hen all the sample has been adsorbed on thegel, alcohol is added to desorb the sample down the column.The hydrocarbons are separated in accordance with theiradsorption affinities into aromatics, olefins, and saturates. Thefluorescent dyes are also separated selectively, with the hydro-carbon types,
21、and make the boundaries of the aromatic, olefin,and saturate zones visible under ultraviolet light. The volumepercentage of each hydrocarbon type is calculated from thelength of each zone in the column.5. Significance and Use5.1 The determination of the total volume % of saturates,olefins, and aroma
