The Picarro G5131-i isotopic and gas concentration analyzer enables simultaneous measurements of site specific and bulk δ15N and δ18O in N2O. It is an ideal solution for discerning and measuring the source of N2O emissions through grab-sample measurements in the lab. The isotopomers of N2O can be used to probe sources and sinks in the global nitrogen cycle by identifying nitrification and denitrification processes in soils and water.
• High-precision at atmospheric concentrations
• δ15N compound-specific and site-specific measurements
• δ18O measurement
• Cryogen-free, continuous operation, field and laboratory deployable
The G5131-i analyzer measures δ15N, δ15Nα, and δ15Nβ with a precision of 0.7 per mil, δ18O with a precision of 0.7 per mil, and N2O concentration with a precision of <0.05 ppb (all precision measurements are at a 10-minute average).

Where the isotopic gas analyzer is used in Thailand
Based on the specifications above, the G5131-i suits laboratories that:
- Need to separate site-specific and bulk δ15N and δ18O values within the same N2O measurement.
- Work with grab samples brought back from soil and water studies to attribute the source of N2O emissions.
- Want to tell nitrification apart from denitrification when tracing sources and sinks in the nitrogen cycle.
- Need cryogen-free continuous operation that can move between the bench and field sites.

Frequently asked questions
What measurement precision does the G5131-i achieve for δ15N and δ18O?
On a 10-minute average it reports δ15N, δ15Nα and δ15Nβ to 0.7 per mil, δ18O to 0.7 per mil, and N2O concentration to better than 0.05 ppb. Our team can walk you through how those conditions apply to your samples.
Why buy PICARRO G5131-i 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 isotopic 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.
