The VOC Continuous Monitoring System is an independent and fully automated measurement system which has been developed to precisely quantify the concentration of ionizable Volatile Organic Compounds (VOCs), in biogas, Renewable Natural Gas (RNG) and Natural Gas. The instrument separates compounds in two independent stages, combining the selectivity of a Gas Chromatograph with the extraordinary sensitivity (low ppbv) of an Ion Mobility Spectrometer (IMS). Two applications are available.
VOC Filter Breakthrough Monitoring
Rather than analyzing hundreds of single compounds by defining evaluation areas on the fixed position of respective compounds, we widened the evaluation area and performed a grid-based analysis that sums up all ionizable VOCs, then monitors the change.
After installing fresh filter media, the first measurements are set as the baseline for a new filter. The sum of individual changes is determined for consecutive measurements. Upon a breakthrough of the filter, the sum will start to increase with elevated compounds and respective concentrations. This will allow operators to monitor the state of the VOC filter media, all at a reasonable cost.
VOC Compound Monitoring
Need to monitor specific VOCs? No problem. Similar to our approach for monitoring nine individual Siloxane compounds, the Ei2300-VOC can be calibrated to measure specific VOC compounds based on your monitoring requirements.
All options are available in configurations suitable for either general purpose or hazardous areas, and can be located indoors or outdoors.
