Source-rock studies to determine potential fuel-bearing and processing characteristics demand reliable analytical data both in the field and laboratory. The CDS 820GS Geochemical Research System has been designed and engineered to provide concerted analytical information, the thermal distillation profile

(P₁, P₂, P₃), and on-line high-resolution FID capillary gc analysis of the P₁ and P₂ composites. P₃ is determined by thermal treatment of the source rock to 390°C by internal trapping and subsequent desorption into a chromatographic column with thermal conductivity detection for carbon dioxide and other evolved gases. These data provide valuable insight into the sample composition, maturation, relation to process yields, and pollution/transport mechanisms.

Illustrations will be given of the organic analysis of kerogens, oil shales, coals, and sediments. The growing significance of analytical pyrolysis combined with concentrator technology will be demonstrated in applications of these advanced configurations dedicated to the geosciences.
