MOCON’s Baseline® 9000 MNME is designed for rapid, continuous measurement of methane, non-methane and total hydrocarbons in gas samples, based on a methane / total hydrocarbon calibration—from sub-ppm to 5,000 ppm (CH4). Applications include VOC continuous emissions monitoring system (CEMS), ambient air quality monitoring networks (AQM), clean rooms (AMC), and air and oxygen purity in air separation units (ASU).

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.

MOCON’s 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.

Features:

  • Automatic adjustment for catalyst efficiency variance
  • All concentrations reported as methane equivalent
  • Flame ionization detector (FID) with automatic ignition
  • Graphical LED display with easy to use menu system
  • Fast (< 30 sec) reproducible response
  • Internal multi-point sampling option
  • Automatic calibration at user-defined intervals
  • Can be calibrated on a CH4 only standard
  • FlowGuard electronic control of fuel, air and sample
  • Electronic back-pressure regulator with sample bypass system
  • Discrete, multilevel concentration & fault alarms
  • Programmable analog output ranges
  • Programmable relays for diagnostics, concentration, alarms, events
  • Remote operation via RS-232 and Ethernet
