The Baseline® 9000 MNME Methane/Total Hydrocarbon Analyzer is designed for rapid measurement of the total hydrocarbons, methane, and non-methane hydrocarbon content in gas samples. The Baseline® 9000 MNME uses a flame ionization detector (FID) in conjunction with an oxidation catalyst switched in and out of a portion of the sample stream. The catalyst oxidizes all hydrocarbons except methane to produce a methane 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.
The Baseline® 9000 MNME 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.
