PyxisGC BTEX
PyxisGC BTEX is a compact gas chromatograph designed for real-time BTEX monitoring in ambient air, including benzene, toluene, ethylbenzene, and xylenes. By using ambient air as its carrier gas, it helps reduce installation complexity, routine service visits, and long-term operating costs for remote air quality monitoring sites.
Carrier-Gas-Free BTEX Gas Chromatograph
Built around a high-sensitivity PID detector and compact MEMS-based hardware, PyxisGC BTEX separates and quantifies benzene, toluene, ethylbenzene, and xylenes at ambient concentrations without a traditional carrier gas cylinder.
Automatic analysis, autocheck, and autocalibration keep the system running unattended in the field, with Pollution Guardian cloud software providing remote access to results and diagnostics.
Designed for ambient monitoring: PyxisGC BTEX supports continuous, unattended BTEX measurement wherever ongoing outdoor air quality data is needed.
Compact BTEX analysis with automatic operation and remote access
PyxisGC BTEX combines high-sensitivity detection, compact hardware, automatic analysis, and cloud-based data tools for field-based environmental monitoring programs.
PID Detector
A 10.6 eV photoionization source gives the detector a benzene detection limit below 0.2 ppb, well within ambient-level BTEX concentrations.
Compact Footprint
The full analyzer fits a 420 mm x 620 mm x 210 mm enclosure while sampling at 250–450 sccm, small enough for shelter or roadside cabinet installs.
Automatic Analysis
Scheduled autocheck and autocalibration routines run automatically in the field, keeping calibration current without a technician on site.
Pollution Guardian
Connects over Ethernet, Wi-Fi, or 4G with MODBUS TCP integration, so results feed directly into a customer’s existing SCADA or data system.
Built for air quality monitoring networks and remote sites
PyxisGC BTEX can be deployed anywhere continuous, unattended BTEX measurement is needed for an air quality monitoring program.
This carrier-gas-free operation is especially valuable at remote or hard-to-access sites, where cylinder logistics would otherwise drive site-visit frequency.
Common Applications
- Smart city air quality: Urban monitoring networks, schools, parks, hospitals, and public areas
- Fence line monitoring: Industrial boundaries, fuel depots, chemical sites, and waste management areas
- Transportation monitoring: Highways, garages, tunnels, airports, stations, and harbors
- Research institutions: Automated ambient air BTEX analysis for environmental studies
Lower maintenance requirements for remote BTEX monitoring
PyxisGC BTEX is designed to simplify long-term field deployment by reducing support needs, lowering site visit frequency, and providing remote access to operating data.
No Carrier Gas Cylinders
Ambient air carrier gas operation eliminates the need for routine carrier cylinder replacement.
Compact Field Deployment
Compact size and low power requirements make the system easier to install, relocate, and integrate into monitoring networks.
Continuous Outdoor Use
Rugged IP55 cabinet construction and automatic system checks support remote ambient monitoring applications.
Pollution Guardian cloud software for real-time data management
Pollution Guardian stores analysis data automatically and allows users to view real-time and historical results, create charts and tables, manage the instrument remotely, and receive user-defined alarms.
Real-Time and Historical BTEX Data
View current and archived monitoring results remotely to better understand air quality trends and site conditions.
User-Defined Alarms and Notifications
Configure data alarms and receive notifications through SMS, email, or smartphone push notifications.
Remote Diagnostics
Support remote instrument review, diagnostics, status checks, and data access without needing to visit the site.
Charts, Tables, and Exports
Create visual data summaries and review BTEX trends for project reporting, site review, and environmental analysis.
