Ambient Air Quality Monitoring Equipment for Non-methane Total Hydrocarbons Detection

Product Introduction

The continuous ambient air monitoring instruments uses the GC-FID method to directly measure the concentration of methane and non-methane hydrocarbons by back-blowing and enrichment of the sample gas, enabling accurate measurement of low The continuous ambient air non-methane monitoring system uses the GC-FID method to directly measure methane and non-methane concentrations by back-blowing and enrichment of the sample gas. The system operates with a constant flow rate of ambient air into the sampling system. After de-dusting, the sample is enriched and removed at low temperature by a large capacity composite enrichment column, the MFC accumulates the sampling volume, the valve is switched and the back-blowing is performed, resulting in a separate peak of non-methane total hydrocarbons and a direct measurement of the concentration.

Product Performance

1. Accurate determination of total non-methane hydrocarbons in ambient air with detection limits at the ppb level.
2. Low-temperature cold trap enrichment and removal technology to improve the accuracy of direct measurement of non-total methane hydrocarbons.
3. Passivation treatment of the internal piping of the instrument, very low adsorption.
4. Full cold point free design for non-destructive testing of high boiling points.
