Portable GC-PID VOC Analyzer
µ-airTOXIC is a portable GC-PID analyzer with pre-concentration for trace-level VOC monitoring. Multiple configurations cover BTEX, 1,3-butadiene and VOCs from C3 to C12, according to the selected method.
The C6-C12 versions include a PAMS configuration for 33 VOCs and a European configuration for 45 VOCs, including terpenes. Optional method libraries extend the available applications.
Applications
- Air-quality monitoring in urban areas, environmental monitoring and refinery fence lines.
- Indoor and outdoor air, industrial hygiene and CO₂ beverages.
Operating principle and field deployment
An electrical six-port valve, a single adsorbent trap and a capillary column are combined with a heated PID and a 10.6 eV lamp. Temperature programming of the column oven and carrier-gas pressure/flow control support the selected analytical method.
- The portable suitcase integrates sampling, analysis, data storage, a battery and an internal nitrogen tank, with readiness for operation in less than 5 minutes.
- Integrated Wi-Fi enables control from a phone, tablet or laptop. A local touchscreen is optional.
- Vistachrom LITE provides measurement configuration, calibration, recalculation, data storage and export.
Options
- Portable permeation oven with certified permeation tubes for calibration; nitrogen generator up to 300 mL/min with an external compressor for operation and/or tank refilling, providing up to 10 hours of operation after refilling.
- Modem support and remote control; purge module for extracting VOCs from water for online BTEX analysis; additional battery.
- Rechargeable internal high-pressure carrier-gas cylinder up to 150 barg; external nitrogen bottle for up to 20 days of operation at 70 bar.
- Multiple methods with a VOC library of more than 40 compounds (µ-airTOXIC C6-C12). Biogenic measurement, including isoprene, is available, with potential co-elution of C4 or C5 ozone VOC precursors.
Application-dependent compliance
The TSP states support for compliance with EN 14662-3:2015 for selected applications and lists EN 15267-1, EN 15267-2 and QAL1. Applicability depends on the selected configuration and application; refer to the TSP for details.
