The PetroAlert® Model 9200 gas analyzer combines the selective detection of a gas chromatograph (GC) with the continuous monitoring abilities of a total hydrocarbon analyzer in a single, sensitive and stable instrument. Specifically engineered to meet the requirements of the oil and gas industry’s exploratory surface-logging process, the analyzer’s speed and accuracy allow surface loggers monitoring a drill site to analyze the hydrocarbons (HCs) within a well while drilling, making for a more timely evaluation of a well’s potential. The Model 9200 incorporates dual-flame ionization detectors (FIDs): one dedicated to the GC and the other to total HC measurement.
