The Picarro G2401 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. It meets the World Meteorological Organization (WMO) and Integrated Carbon Observation System (ICOS) performance requirements for CO, CO2, and CH4 atmospheric monitoring.
• Simultaneous and continuous measurement of four atmospheric trace gases
• Parts-per-billion sensitivity, precision, and accuracy with exceptionally low drift
• Compliant with WMO and ICOS international ambient atmospheric monitoring requirements
• Water correction automatically reports dry gas mole fractions
Precision at 5 seconds, 5 minutes, and 60 minutes is 15, 1.5, and 1 ppb for CO; 50, 20, and 10 ppb for CO2; and 1, 0.5, and 0.3 ppb for CH4. Maximum drift at standard temperature and pressure (STP) over 24 hours is 10 ppb for CO; 100 ppb for CO2; and 1 ppb for CH4. Water correction software automatically reports dry gas mole fractions to help reduce research complexity and consumable costs.
PICARRO G2401 in Thailand
The Picarro G2401 is a greenhouse gas analyzer that follows carbon monoxide, carbon dioxide, methane and water vapor simultaneously for atmospheric and emissions work, and Thai Unique supplies and supports it in Thailand.

Where the greenhouse gas analyzer is used in Thailand
Based on the specifications above, the G2401 suits laboratories and monitoring teams that
- Need to track CO, CO2, CH4 and water vapor side by side, without interruption, for atmospheric science studies
- Run ambient air monitoring that has to satisfy WMO and ICOS (Integrated Carbon Observation System) network performance requirements for CO, CO2 and CH4
- Work on air quality or emissions quantification and rely on ppb-level readings that barely drift over 24 hours
- Want the analyzer to report concentrations on a dry basis (dry mole fraction) automatically, with the effect of water vapor removed, keeping data handling simpler and consumable spending lower
Service and support in Thailand

- Scheduled preventive maintenance — year-round cover under a Service Contract, with costs you can budget for
- Repairs with genuine spare parts — experienced technicians using original components from the manufacturer
- Operator training — classroom and hands-on training on your own instrument
- Sample testing and method verification — we run your real samples and verify the method before you commit
Frequently asked questions
How precise and stable is the G2401 for CH4, CO2 and CO?
Averaged over 60 minutes, precision reaches 0.3 ppb for CH4, 10 ppb for CO2 and 1 ppb for CO. Maximum 24-hour drift at STP is 1, 100 and 10 ppb for the same gases, and our team can take you through the full specification.
Why buy PICARRO G2401 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 greenhouse gas 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.
