standard by ASTM International, 10/01/2009

Document Format: PDF

Description

1.1 This test method covers an analytical scheme using the mass spectrometer to determine the hydrocarbon types present in virgin middle distillates 204 to 343°C (400 to 650°F) boiling range, 5 to 95 volume % as determined by Test Method D86. Samples with average carbon number value of paraffins between C12 and C16 and containing paraffins from C10 and C18 can be analyzed. Eleven hydrocarbon types are determined. These include: paraffins, noncondensed cycloparaffins, condensed dicycloparaffins, condensed tricycloparaffins, alkylbenzenes, indans or tetralins, or both, CnH2n-10 (indenes, etc.), naphthalenes, CnH2n-14 (acenaphthenes, etc.),
CnH2n-16 (acenaphthylenes, etc.), and tricyclic aromatics.

Note 1 – This test method was developed on Consolidated Electrodynamics Corporation Type 103 Mass Spectrometers.
