Heated Gaseous Hydrocarbon Analyzer

  • EPA Method 25A
  • 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 H Heated Hydrocarbon Analyzer is a microprocessor based instrument designed for continuous ambient or process hydrocarbon gas measurement in environmental or industrial settings. The analyzer is configured for single point analysis (with or without a sample pump) of samples heated up to 376 °F (191 °C) for pre-filtered (< 10 microns) non-condensing samples.

    Detection limits down to < 0.1 ppm. User-programmable ranges from 10 ppm to 10% (propane) or 10 ppm to 50% (methane) are factory-configured per the customer’s application to facilitate installation and setup.


    Using a Flame Ionization Detector (FID), AMETEK MOCON Baseline® FlowGuard electronic control regulates the delivery of fuel, air, and a small portion of the sample gas, to the FID. During the combustion process, organic or hydrocarbon-based gases in the sample are ionized, detected by the instrument, and then reported as a concentration. The automatic calibration feature enhances the long-term analytical stability of the instrument.


    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 H analyzer includes a 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.
