THC & Methane Analyzer

THC & Methane Analyzer



THC & Methane Analyzer is designed to minimize the loss of hydrocarbons prior to analysis by maintaining the required temperature through use of a single heated filter, single heated sample line and stainless steel fittings, all of which have low hydrocarbon adsorption characteristics. The system has been designed to endure the harsh environment of the in-use test application while maintaining laboratory grade measurement standards.


  • Automatic Flame Ignition: The FID flame will light automatically after approximately 30 minutes of warm-up time.
  • Dual Flame Ionization Detector Assembly: The single assembly dual detector system, coupled with an NMHC cutter assembly upstream the CH4 FID, provides both THC and CH4 measurements in real-time using only 1 sample line, 1 FID fuel line and 1 combustion air input.
  • Measuring Range: The Dual FID has 4 user-selectable measurement ranges for each channel, ranging from 0-100 ppmC1 and 0-30000 ppmC1.
  • Sample Handling: A water trap and Nafion dryer are integrated into the SEMTECH SCS module. A heated sample line (length varies with tested vehicle) delivers the sample to the Dual FID chamber at 191°C. Particulate matter is removed using a built-in, disposable, user-replaceable filtration system.
  • Combustion Air: The Dual FID module includes a built-in catalytic converter for removal of all hydrocarbons from ambient air, thus providing hydrocarbon-free combustion air to the system.
  • NMHC Cutter: The system includes a built-in NMHC catalytic oxidation assembly for removal of the NMHC fraction from sample prior to analyzing the sample using the Dual FID’s methane channel.
  • Compliance: The SEMTECH Dual FID is compliant for gases regulated under the rules of UN-ECE. Reg. 49 and E.U. Commission Regulation No. 582/2011 and of US EPA 40CFR, Part 1065.
  • Heated Lines: Sensors, Inc. has developed an innovative, low powered heated line that controls and maintains the temperature of the exhaust sample at 191 ±5°C.
  • 12V DC Power: The system operates on 12V DC power.
