Gas Chromatographic/Mass Spectrometric Analysis of Paraho Shale Oil

Source

Paraho shale oil <260°C (500°F) was analyzed by gas chromatography/mass spectrometry (GC/MS) with the intent of establishing a preliminary set of guidelines and conditions under the auspices of ASTM for the GC/MS analysis of shale oil. A 60-m DURABOND-1, DB-1, fused silica capillary column coupled directly to our fast scanning 7070H double-focusing mass spectrometer was chosen. GC/MS operating parameters were selected so that the total ion monitor (TIM), GC trace would match that of a flame-ionization detector (FID) GC trace obtained previously under optimized conditions for a DB-1 column. Preliminary results show the presence of homologs of n-alkanes, isoalkanes, alkenes, or cyclic alkanes, alkylbenzenes, naphthalenes, indanes, tetralins, thiophenes, pyridines, indoles, phenols, and so forth. The data were reduced using an automatic quantitation INCOS computer procedure designed by J. Karnofsky specifically for this laboratory.
