The Picarro G2103 gas concentration analyzer provides precise, real-time measurement of ammonia (NH3) and water (H2O) vapor. It incorporates coated components in the critical gas pathway. This reduces the propensity of NH3 molecules to adhere to pathway surfaces, which improves measurement response time. The analyzer is an ideal solution for sensitive trace and ambient ammonia research and monitoring applications, such as livestock emissions on farms and formation of particle matters from ammonia in urban areas.
- Fast, continuous, real-time measurement of NH3
- Long-term stability for infrequent calibration
- Small footprint, field or lab deployable with no consumables required
- Water correction automatically reports dry gas mole fractions
Precision at 1 second, 10 seconds, and 5 minutes is 500, 170, and 30 and parts-per-trillion (ppt). Rise time (10 – 90%) and fall time (90 – 10%) is less than 2 minutes for 20 parts-per-billion (ppb) NH3 challenge. Drift at standard temperature and pressure (STP) over 72 hours is ± 0.15 ppb. Water correction software automatically reports dry gas mole fractions to help reduce research complexity and consumable costs.

Where the gas concentration analyzer is used in Thailand
Based on the specifications above, the G2103 suits laboratories and field teams that:
- Need to follow ammonia at trace and ambient levels, with precision reaching 500, 170 and 30 parts-per-trillion at 1 second, 10 seconds and 5 minutes respectively.
- Work with livestock emissions on farms, or study how ammonia contributes to the formation of particle matter over urban areas.
- Want to capture fast concentration changes, with rise and fall times of under 2 minutes for a 20 parts-per-billion ammonia challenge, helped by coated components in the critical gas pathway that limit ammonia sticking to surfaces.
- Need to run long unattended campaigns, with infrequent calibration, no consumables, and drift of ±0.15 ppb over 72 hours at standard temperature and pressure.
Service and support in Thailand

- Sample testing and method verification — we run your real samples and verify the method before you commit
Frequently asked questions
How does the G2103 handle humidity in the sample when it reports ammonia?
Water correction software runs automatically and reports concentrations on a dry basis (dry mole fraction), with the effect of water vapour removed. This keeps sample handling simpler and consumable costs down. Our team can walk through how this fits your sampling setup.
Why buy PICARRO G2103 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.
