- Model 9000 MNME - Methane/Non-Methane Analyzer



The Baseline 9000 MNME uses a flame ionization detector (FID) in conjunction with an oxidation catalyst switched in and out of the sample stream. The catalyst oxidizes all hydrocarbons except methane to produce a methane only measurement. This catalytic reaction relies on the presence of oxygen (O2) in the sample. The methane value is then subtracted from the total hydrocarbon concentration to determine the non-methane hydrocarbon reading. Output options include analog, digital and logic capabilities.

Gaseous Non-Methane Hydrocarbon Analyzer

  • For cleanroom, environmental, and process applications
  • FlowGuard control of fuel, air, and sample with automatic shut-off
  • Provides methane, non-methane, and total hydrocarbon concentrations
  • Graphical LCD display with easy to use menu

The analyzer provides fast data handling and highly reproducible results. Errors commonly associated with catalyst characteristics have been eliminated providing an extremely stable and accurate signal. Because the non-methane signal is the difference in the two measured quantities, it is more stable, thus greatly reducing its systemic zero drift. The non-methane signal response factor is adjusted and thus closely correlates to the carbon number. This analytic method eliminates integration errors that can be present in gas chromatographic (GC) methods.

The Baseline 9000 MNME can be configured with internal components for single or multi-point analysis of non-condensing gas samples. The automatic calibration feature enhances the long-term analytical stability of the instrument.

The instrument provides access to operating parameters and concentration data through an RS-232 or Ethernet port. A simple ASCII, tab delimited protocol has been implemented. The ASCII data can be acquired by an external PC running a basic communications program such as Windows® Hyper Terminal 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.
