FAQ: eGC Data Stream and ChemRows Software

The ENMET eGC is a cost-effective solution for detecting benzene at trace levels (sub ppb) in both workplace and fenceline environments, capable of analyzing complex gas mixtures. This autonomous field instrument operates using only solar power, allowing for convenient deployment to remote sites and emission areas. Additionally, ENMET provides expert technical assistance, including problem assessment, product selection, system installation, and training.

What is the purpose of combining eGC data stream with GIS and local meteorology data?

The combination of eGC analysis data with GIS and local meteorology data focuses on wind speed and direction to create an action plan for site emissions reduction, providing a critical understanding of the time-based emission profile.

How does ChemRows software work?

ChemRows is a fusion of eGC analysis data with local weather station meteorological data using wind speed and direction, creating graphical vectors that provide a local weather input correlated with concentration data unique to a specific geographic location.

What are the key features of ChemRows software?

• Combines eGC analysis data with local weather station meteorological data
• Uses wind speed and direction to create graphical vectors
• Displays concentration and meteorology data as directional vectors on a GSI map, changing position over time
• Utilizes a color-coding system based on concentration values for wind vector display

How do the wind vectors in ChemRows software represent concentration levels?

The length of the wind vector is proportional to wind speed, while the direction points from the bullseye location (eGC) to the origination of the wind. The color-coding system displays:

• 0-2.79 ppb as blue (below target action level)
• 2.8-199.9 ppb as red
• Above 200 ppb as purple

Can ChemRows software be used to create a time-lapse video?

Yes, the data stream can be combined into a time-lapse video, creating a graphical representation of emission changes over time.

How does using multiple eGCs enhance the effectiveness of ChemRows software?

By utilizing an array of eGCs, you can observe the correlation of readings from different locations together in one graphic representation, providing a near real-time picture of what is occurring across the facility and taking into consideration local meteorological conditions.

Can the eGC's self-contained mobile platform be used to relocate the unit?

Yes, the eGC's powerful combination of solar array, reference calibration standard, and meteorological station data allows for easy relocation of the unit using the mobile platform, making it a convenient way to make changes to the eGC's location.

How has ChemRows software been proven useful?

The approach has been field-proven to be a very useful tool for emission level remediation and subsequent corrective action decisions.
