Nutech 3000 Portable THC & NMHC Analyzer

The Nutech 3000 THC (Total Hydrocarbons) & NMHC (Non-Methane Hydrocarbons) Analyzer is suitable for portable monitoring of TVOC (Total Volatile Organic Compounds), CH4 (Methane) and NMHC in stationary source emission and fence line.

Technology Principle

TVOC can be represented by THC or NMHC. The Nutech 3000 adopts catalytic oxidation + double FIDs technology to simultaneously analyzes THC & NMHC.

The sample gas is introduced to the analyzer by 2 channels. FID 1 analyzes the concentration of THC (total hydrocarbons) of the gas sample in channel 1. And the catalytic oxidation module oxidizes the NMHC (non-methane hydrocarbons) into CO2 and H2O in channel 2 and thus FID 2 only analyzes the concentration of methane. The concentration of NMHC can be calculated by concentration of THC subtracts the concentration of methane.

Concentration of NMHC = Concentration of THC – Concentration of CH4
