Two Instruments In One

The Baseline PetroAlert® Model 9200 gas analyzer combines the selective detection of a gas chromatograph (GC) with the continuous monitoring abilities of a total hydrocarbon analyzer (THA) in a single, compact, sensitive and stable instrument.

The PetroAlert Model 9200 is specifically engineered to meet the requirements of the oil and gas industry’s exploratory well-logging process. Its speed and accuracy allow well loggers monitoring a drill site to analyze the hydrocarbons within a well both quantitatively and qualitatively, while drilling. That ability makes for a more efficient drilling process and more timely evaluation of a well’s potential. Each PetroAlert is factory configured to meet specific customer monitoring requirements.

The PetroAlert Model 9200 incorporates dual-flame ionization detectors (FIDs): one dedicated to the GC and the other dedicated to total hydrocarbon measurement. The GC performs fast C1 to C5 analysis (< 30 seconds, preserving the C1-C2 separation at 200:1 concentration ratios) with a detection limit of < 10 ppm as methane (CH4), while the total hydrocarbon detector continuously monitors total hydrocarbons down to 0.003% and up to 100% as CH4. The analyzer's automatic calibration feature is ideal for unattended operation.

The microprocessor-based PetroAlert is controlled by a fully integrated and powerful icon-based system software—eliminating the need for an external PC. The analyzer receives instructions either directly—using a programmable touchscreen on the front panel—or through remote access when the analyzer is connected to an Internet-accessible network and utilizing the free PC software provided with each instrument. The analyzer’s data collection features include chromatograms and user-definable options for exporting data to logging software. Data storage options are either continuous or based on events, such as alarms.

Baseline’s PetroAlert analyzers are industry proven and adopted worldwide by major oil and petrochemical companies, as the finest FID-based hydrocarbon field analyzers available while providing automated lab quality data.
