THC-CH4-NMHC Analyzer

Model N901 - Teledyne Advanced Pollution Instrumentation (TAPI)

The Model N901 is a near-continuous hydrocarbon gas analyzer that measures the concentration of Methane (CH4) and Total Hydrocarbons (THC) in air. The concentration of the non-Methane (NMHC) component is calculated by the subtraction of CH4 from THC, with high sensitivity and accuracy. The hydrocarbons are measured using a Flame Ionization Detector (FID), in combination with gas chromatography (GC). The instruments range and performance are tuned specifically for use in ambient air quality monitoring assessments.
