More D These boiling point distributions provide information as to the potential mass percent yield of products. This test method may provide useful information that can aid in establishing operational conditions in the refinery. Knowledge of the amount of residue produced is important in determining the economics of the refining process.

This document has been replaced. View the most recent version. The amount of residue or sample recovery is determined using an external standard. This temperature corresponds to the elution of n -C This test method uses capillary columns with thin films, which results in the incomplete separation of C 4 -C 8 in the presence of large amounts of carbon disulfide, and thus yields an unreliable boiling point distribution corresponding to this elution interval. In addition, quenching of the response of the detector employed to hydrocarbons eluting during carbon disulfide elution, results in unreliable quantitative analysis of the boiling distribution in the C 4 -C 8 region.
Since the detector does not quantitatively measure the carbon disulfide, its subtraction from the sample using a solvent-only injection and corrections to this region via quenching factors, results in an approximate determination of the net chromatographic area. A separate, higher resolution gas chromatograph GC analysis of the light end portion of the sample may be necessary in order to obtain a more accurate description of the boiling point curve in the interval in question as described in Test Method D see Appendix X1.
The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

The Crude Oil Analyzer ASTM D is the official standard for determination of the boiling point distribution and cut point intervals of crude oils and residues by using high temperature gas chromatography. As a result of this merge, more accurate boiling point range data is obtained allowing precise cut point intervals determination for the whole crude oil. This allows for modeling end product closer to specs and ultimately less product give-away, while still meeting stringent product specifications. Crude oil.
