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&degC (400 to 650&degF) boiling range, 5 to 95 volume% as determined by Method D86. Samples with average carbon number value of paraffins between C 12 and C 16 and containing paraffins from C 10 and C 18 can be analyzed. Eleven hydrocarbon types are determined. These include:paraffins, noncondensed cycloparaffins, condensed dicycloparaffins, condensed tricycloparaffins, alkylbenzenes, indans or tetralins, or both, CnH n- 10 (indenes, etc.), naphthalenes, CnH n- 14 (acenaphthenes, etc.), CnH n- 16 (acenaphthylenes, etc.), and tricyclic aromatics.

Note 1-This test method was developed on consolidated Electrodynamics Corp. Type 103 Mass Spectrometers.
