The AQ7100 Micro Ambient Air Quality Monitoring System is a low-cost, multi-parameter integrated compact ambient air monitoring system developed by WAYEAL based on its extensive experience in the environmental monitoring field. Through a scientific and rational 'combined point placement' deployment scheme, the system targets various monitoring objects and parameters such as urban residential areas, industrial parks, regional boundaries, road traffic, and pollutant transmission channels, forming a 'group-prevention' collaborative monitoring network and a professional data calibration system. It achieves full coverage of the environmental monitoring network, enables high temporal-spatial resolution air pollution monitoring, and combines information-based big data applications to realize pollution source tracing, early warning and forecasting, providing timely and effective decision support for environmental pollution prevention and control.

Detection Method: GC-FID Measurement Method: 直测法（Direct Measurement） Measured Components: 甲烷、非甲烷总烃（CH4、NMHC）

The AQ7800 is a methane and non-methane hydrocarbon analyzer independently developed by WAYEAL for direct measurement of non-methane total hydrocarbons (NMHC) in ambient air. Based on the GC-FID method, the instrument performs backflushing and enrichment processing on the sampled gas to directly measure methane and NMHC concentrations, enabling accurate measurement of higher-concentration NMHC. It complies with HJC-ZY84-2020 'Technical Requirements and Detection Methods for Ambient Air Non-Methane Total Hydrocarbons Continuous Monitoring System'. During operation, ambient air enters the sampling system at a constant flow rate; after dust removal, it is enriched and dehydrated at low temperature through a large-capacity composite trap column. With MFC superimposed sampling volume, valve switching and backflushing, methane and total hydrocarbons are separated into individual peaks for direct concentration determination. The fully heat-traced detection module effectively prevents loss of high-boiling-point and high-concentration samples, achieving a detection limit of ≤1ppbC, superior to the 20ppbC required by the latest standard.
