Total Hydrocarbon Analyzer

HydrocarbonThe Baseline® Series 9000 is the candidate of choice whenever accurate, reliable total hydrocarbon analysis is required. The Series 9000 analyzer provides unparalleled flexibility and offers continuous, fully automated gas analysis over a broad range of concentrations.

The 9000 has a dynamic range from less than 10 ppb on the low range version and up to 100% as methane on the high range version. The analyzer has a generous complement of analog, digital and logic output capabilities.


The Series 9000 is designed to continuously monitor the total hydrocarbon content of non-condensing gases in a variety of applications, such as:

  • Beverage grade CO2 analysis
  • Scrubber & oxidizer efficiency
  • Carbon bed breakthrough detection
  • Contaminant analysis in pure/ultrapure inert gases
  • Well logging
  • Industrial hygiene & safety monitoring
  • Fenceline (perimeter) monitoring around industrial sites
  • LEL monitoring
  • Flame ionization detector.
  • 3U case, 19″ (48.3cm) rack mountable.
  • Automatic calibration at user-defined intervals.
  • Internal, multipoint sampling option.
  • FlowGuard electronic control of fuel, air and sample.
  • Electronic back-pressure regulator with sample bypass system ensures fast response.
  • Discrete, multilevel concentration & fault alarms.
  • Analog output ranges programmable from 1ppm – 100% full scale.
  • Programmable relays for concentration alarms, events and diagnostics.
  • Automatic FID ignition, with automatic shut-off of sample, fuel and combustion air.
  • Remote operation via RS-232 and Ethernet.
  • Graphical display and easy to use menu system.
  • Optional 9000 Keeper software to monitor and control the instrument remotely.
