Dear Friends,
we received one new equipment for ASTM D7096, is it possible to match the results with ASTM D86 normal distillation method. Please reply..

ASTM D7060
1. Scope
1.1 This test method covers the determination of the boiling range distribution of gasoline and liquid gasoline blending components. It is applicable to petroleum products and fractions with a final boiling point of 280 °C (536 °F) or lower, as measured by this test method.
1.2 This test method is designed to measure the entire boiling range of gasoline and gasoline components with either high or low vapor pressure and is commonly referred to as Simulated Distillation (SimDis) by gas chromatographers.
1.3 This test method has been validated for gasoline containing ethanol. Gasolines containing other oxygenates are not specifically excluded, but they were not used in the development of this test method.
D86 falls into this method application range, but not reverse.
They should correlate in intersection boiling temp range for non-oxygenated fuel blends. But taking in account that GC separation just sorts substances by their boiling temperatures - oxygenates should not significantly distort the results.

Nizar84,
If you are using a commercial software package - then yes. I know Separation Systems software offers a D86 glass correlation and I believe that Envantage Dragon software does as well.
Works quite well so far.
Best regards,
