The Picarro G2401-m gas concentration analyzer provides simultaneous, precise measurement of carbon monoxide (CO), carbon dioxide (CO2), methane (CH4) at parts-per-billion (ppb), and water (H2O) vapor at parts-per-million (ppm) sensitivity with negligible drift for atmospheric science, air quality, and emissions quantification. Flight-optimized design elements minimize effects of aircraft vibration, pitch, roll, and rapidly changing ambient conditions. As a result, the analyzer can be operated on aircraft for urban mapping or vertical profiles.
• Simultaneous and continuous measurement of four atmospheric trace gases
• Parts-per-billion sensitivity, precision, and accuracy with exceptionally low drift
• Rugged design for guaranteed performance during flight
• Water correction automatically reports dry gas mole fractions
Precision at 5 minutes with vibration at 20 Hz, 1 g and 60 minutes is ≤30 ppb for CO; ≤200 ppb for CO2; and ≤2 ppb for CH4. Drift at standard temperature and pressure (STP) over 24 hours is ≤15 ppb for CO; ≤200 ppb for CO2; and ≤1.5 ppb for CH4. Drift remains low with changing temperature and pressure (see data sheet for details). Water correction software automatically reports dry gas mole fractions to help reduce research complexity and consumable costs.
PICARRO G2401-m In-flight in Thailand

Where the gas concentration analyzer is used in Thailand
Based on the specifications above, the G2401-m In-flight suits laboratories and research teams that
- Need to map CO, CO2 and CH4 across a city from an aircraft instead of relying only on fixed ground stations
- Want to build vertical profiles of trace gases while the aircraft climbs or descends
- Work on emissions quantification or air quality projects where ppb-level precision and low drift decide whether the data can be trusted
- Want the analyzer to report concentrations on a dry basis (dry mole fraction) automatically, with the effect of water vapor removed, keeping the workflow simpler and consumable costs down

Frequently asked questions
How well does the G2401-m hold its precision with the vibration of an aircraft?
Its flight-optimized design is built to limit the effects of vibration, pitch, roll and fast-changing ambient conditions, and under vibration at 20 Hz and 1 g the stated 5-minute precision is ≤30 ppb for CO, ≤200 ppb for CO2 and ≤2 ppb for CH4. For drift under changing temperature and pressure, talk to our team and we will go through the data sheet with you.
Why buy PICARRO G2401-m In-flight from Thai Unique rather than direct from the manufacturer?
Because the people who look after it are here. Installation, calibration, scheduled maintenance, repairs with genuine parts and operator training are all handled by our team in Thailand, without routing every request overseas.
Can we test our own samples before deciding?
Yes. Our sample testing and method verification service runs your real samples so you can see the results this gas concentration analyzer gives on your workload before you buy.
How much does it cost, and how do we request a quotation?
Pricing depends on the configuration, accessories and the scope of work in your laboratory. Tell our sales team what you need to analyse and how many samples you run per day, and we will propose a configuration together with lead time and service terms.
