- Model 9000 TCA - Total Carbon Hydrocarbon/CO/CO2 Analyzer



The Baseline 9000 TCA Total Carbon Analyzer is a microprocessor-based instrument designed to measure total hydrocarbon content as well as provide a combined carbon monoxide (CO) and carbon dioxide (CO2) reading for impurity detection at industrial and specialty gas companies. Detection limits down to < 0.1 ppm. User-programmable ranges from 1 ppm to 100 ppm are factory-configured per the customer’s application to facilitate installation and setup.

  • Gaseous Hydrocarbon/CO/CO2 Analyzer
  • Hydrocarbon and CO/CO2 Impurities in ultra-pure gasses
  • Accurate, continuous, detection
  • FlowGuard control of fuel, air, and sample with automatic shut-off
  • Graphical LCD display with easy to use menu

The Baseline 9000 TCA uses a flame ionization detector (FID) in conjunction with a methanizing catalyst switched in and out of the sample stream. The catalyst converts CO and CO2 to methane to produce a total carbon reading. This catalytic reaction relies on the hydrogen (H2) in the fuel stream. The hydrocarbon only value is then subtracted from the total carbon concentration to determine the CO / CO2 reading.

All instrument parameters are reported clearly and continually refreshed on a large, graphical LCD display. Using analog, digital, and logic output communication capabilities, analytical information from the analyzer can be acquired using an external PC and a simple communications program such as Windows HyperTerminal or the analyzer can output binary or ASCII formats directly to a data acquisition system or PLC. Every Baseline 9000 analyzer includes AMETEK MOCON's free PC utility 9000 Keeper used for storing and uploading multiple methods, as well as sending configuration settings, directly to the analyzer.
