eGC Gas Chromatography Analyzer

eGC (environmental gas chromatography analyzer) represents a new cost effective approach to gas chromatographic monitoring products for field applications. It is capable of multi-component analysis at trace environmental concentration levels, sub part per billion, ideal for ambient air fenceline monitoring applications.

The eGC is a significant technological improvement over traditional process gas chromatographs configured for ambient air monitoring. It is a fully autonomous instrument requiring no external carrier gas support. Additionally, it can be configured to operate using solar power, allowing convenience of deployment to remote areas. All analysis data is communicated via a cellular modem to the cloud where it can be easily accessed and shared. eGC has been tested top operate outdoors under harsh real work ambient conditions (-10 to 45°C) and is capable of the accuracy and precision of an analytical laboratory instrument.

Using gas chromatography as it method of analysis, eGC separates the components of a workplace ambient air sample to allow the target chemicals to be easily detected. This allows a phased real time measurement of a variety of threat chemicals such as benzene or vinyl chloride in the field.

Analysis begins by collecting a composite air sample using a high volume transport fan, where a small air sample is collected for analysis; this sample is collected on the sample modular or pre-column. This sample is transferred to the chromatographic column for separation. As the chemicals elute from the column they are detected by the sensor. The sensor measures a change of state of difference over time, which causes the sensor baseline frequency shift at a specific time for a specific chemical. This change will be compared to reference calibration and the result will be reported in concentration units typically ppb (parts per billion). The typical sample analysis takes 2 to 5 minutes to complete and the cycle repeats on a continuous basis.

eGC is very economical to deploy and sustain in the field. Calibration checks are run as programmed to a known standard at a specific time and interval. The general service interval is 6 months where you would replace only the carrier scrubber. eGC is a next generation solution for trace chemical fenceline analysis for a broad spectrum of industrial chemicals.
