PyxisGC BTEX<\/h1>\n

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.<\/p>\n\n

\n Product Overview<\/span>\n

Carrier-Gas-Free BTEX Gas Chromatograph<\/h2>\n

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.<\/p>\n

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.<\/p>\n <\/div>\n\n

\n Key Capabilities<\/span>\n

Compact BTEX analysis with automatic operation and remote access<\/h2>\n

PyxisGC BTEX combines high-sensitivity detection, compact hardware, automatic analysis, and cloud-based data tools for field-based environmental monitoring programs.<\/p>\n <\/div>\n\n

\n
\n Detection<\/span>\n

PID Detector<\/h3>\n

A 10.6 eV photoionization source gives the detector a benzene detection limit below 0.2 ppb, well within ambient-level BTEX concentrations.<\/p>\n <\/div>\n\n

\n Footprint<\/span>\n

Compact Footprint<\/h3>\n

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.<\/p>\n <\/div>\n\n

\n Operation<\/span>\n

Automatic Analysis<\/h3>\n

Scheduled autocheck and autocalibration routines run automatically in the field, keeping calibration current without a technician on site.<\/p>\n <\/div>\n\n

\n Software<\/span>\n

Pollution Guardian<\/h3>\n

Connects over Ethernet, Wi-Fi, or 4G with MODBUS TCP integration, so results feed directly into a customer’s existing SCADA or data system.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/section>\n\n <\/div>\n<\/div>\n\n\n\n

Built for air quality monitoring networks and remote sites<\/h2>\n

PyxisGC BTEX can be deployed anywhere continuous, unattended BTEX measurement is needed for an air quality monitoring program.<\/p>\n

This carrier-gas-free operation is especially valuable at remote or hard-to-access sites, where cylinder logistics would otherwise drive site-visit frequency.<\/p>\n\n
