- Soil flux studies: Ideal for measuring gas exchange between soil and atmosphere in the field.
- Greenhouse gas monitoring: Simultaneously measures CH₄ and CO₂ on-site.
- Natural gas leak detection: High-sensitivity detection, over 1,000× more sensitive than conventional methods.
- Compliance monitoring: Supports adherence to air quality regulations.
- Air quality studies: Suitable for general air quality measurements in various environments.
- Field sampling: Operates across a wide sample temperature range of −40 to 50 °C.
Microportable gas analyzers GLA131 Series
Sensitive, precise, accurate, highly linear (wide dynamic range) and fast.
Pre-calibrated analyzer in extremely compact crushproof enclosure weighing less than 6 kg. Operates directly on AC or DC power. Battery recharges when analyzer connected to AC. System includes all software for analysis and an internal vacuum pump for less than 0.4 second gas flow response.
The GLA131-GGA starts recording data within 20 seconds after power on so users do not have to wait for a long warm-up period for the system to thermally equilibrate. ABB’s patented OA-ICOS technology, a fourth-generation cavity enhanced absorption technique, has many advantages overolder, conventional and delicate cavity ringdown spectroscopy and direct absorption techniques. ABB analyzers are easy to operate and robust, thus providing users with higher performance and reliability at minimal operating costs.
The GLA131-GGA analyzer has an internal computer that can store data practically indefinitely on an SD card and send real time data to a tablet, smartphone or other WiFi device. The analyzer includes control and analysis software.
