Airzone has extensive experience in real-time air monitoring. Real-time monitoring provides measurements of airborne levels of contaminants continuously. In contrast to integrative measurement methods where the results of the measurement are not available until some time after the measurement, real-time monitoring results are reported continuously.
We have provided real-time measurements for clients for a wide range of target compounds. For example, real-time monitoring was conducted for aircraft emissions at a Caribbean airport with a mobile trailer measuring ambient concentrations of CO, SO2, NO2 and TSP using electronic CEM analyzers (Teledyne models) including gas filter correlation CO analyzers, UV fluorescent SO2 analyzers, chemiluminescent NOx analyzer and E-Bam particle samplers at 1-minute intervals. These monitors are typically used to monitor ambient air quality to ensure compliance with government air quality standards. The CEMs were calibrated before and after sampling intervals with certified gases. VOCs were monitored with a Syntech Spectras GC (gas chromatograph) equipped with a photo ionization detector (PID). Data from the GC as well as data from the CEMs were recorded on an Opsis DL 256 PRO data system.
