The Picarro G2204 gas concentration analyzer provides simultaneous, precise measurement of methane (CH4) and hydrogen sulfide (H2S) at parts-per-billion (ppb) sensitivity with negligible drift for emissions measurements from landfills, refineries, paper mills, or industrial plants. It can be installed in minutes for stationary monitoring, or it can be coupled using U.S. Environmental Protection Agency geospatial methods for beyond the fence line remote emissions quantification (EPA Other Test Methods 33).
- Real-time CH4 and H2S measurements for fenceline monitoring and mobile surveys Best-in-class sensitivity for the most demanding regulatory requirements
- Excellent stability and continuous operation minimize downtime and data gaps
- Easy operation and no consumables or pre-concentration reduce costs
- Small footprint and quick installation simplify new deployments
CH4 precision at 5 minutes is 0.5 ppb (1 sigma). H2S precision at 5 minutes is 1 ppb (1-sigma), with an LDL of 3 ppb (3-sigma). Maximum drift at standard temperature and pressure (STP) over 24 hours is <2 ppb for CH4 and <3 ppb for H2S (peak-to-peak, 50-min average). Users can connect remotely and control the analyzer through a standard remote desktop connection or with similar remote login software, and the analyzer can be configured to automatically send out measurement data at regular intervals.

Where a gas concentration analyzer is used in Thailand
Based on the specifications above, the G2204 suits teams and laboratories that
- Need to track methane and hydrogen sulfide emissions from landfills, refineries, paper mills or industrial plants in real time
- Work with fenceline monitoring programmes or mobile survey routes where readings must follow the vehicle or the site boundary
- Want to quantify emissions beyond the fence line using EPA geospatial approaches such as Other Test Method 33
- Need continuous unattended operation without consumables or pre-concentration steps, with remote access to the analyzer and scheduled data delivery
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 is the G2204 for methane and hydrogen sulfide, and how much drift should we expect?
At a 5-minute averaging time the analyzer reaches 0.5 ppb (1 sigma) for methane and 1 ppb (1 sigma) for hydrogen sulfide, with a 3 ppb lower detectable limit (3 sigma) for H2S, while 24-hour drift at standard temperature and pressure stays below 2 ppb for CH4 and 3 ppb for H2S. Talk to our team in Thailand if you would like these figures reviewed against your monitoring plan.
Why buy PICARRO G2204 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.
