6000C NMOC Online Analyzer 

The 6000C is designed for online monitoring of methane/non-methane total hydrocarbons (NMOC/NMHC) in ambient air and at the fenceline. The 6000C applies a preconcentration technology and the most reliable FID to producing stable data, which are continuously uploaded to environmental management system.

    Technical Data



    Measurement Range

    0.1 ppb to ppm level

    Analysis Time







    Ultrapure N2H2 or Air

    Operating Environment

    110V/60Hz or 220V/50Hz±10% with max. 1000W, 10~40/20%~90%RH operating range


    The original low-temperature preconcentration technology increases the air sampling volume to 500-1000ml, lowers the detection limit of NMHC to sub-ppb level (ordinary FID responds to 1 ppm of air VOC), and meets the detection requirements of low or ultra-low concentration air VOC.

    The 6000-C can effectively dehydrate and separate non-methane total hydrocarbons and methane by using composite adsorption based on Tenax adsorbent and appropriate flow control. Then it can be directly analyzed by FID.

    With Nutech®’s FID, it has good response, wide linear range, and automatic realtime flameout protection function.

    The 6000-C uses MFC after traps to eliminate crossover contamination and accurately control the flow rate to effectively ensure the accuracy of test results.

    It has PC control, real-time data acquisition and transmission, automatic process data recording and storage, and supports QC/QA report printing. The system can automatically save and restore data if there is an unexpected power outage.
