The Picarro L2140-i isotopic water analyzer enables simultaneous measurements of δ18O, δ17O, and δ2H in solids, liquids and vapor. In addition, the analyzer determines 17O-excess to sub 15 per meg (<0.015‰). Measurements of 17O-excess in conjunction with high precision measurements δ18O and δ2H enable geoscientists to enhance our understanding of present day climate and the interactions between the hydrosphere and biosphere and to help reconstruct climates of the past. The ability to quantify extremely small deviations in δ17O (i.e., 17O-excess), typically less than 0.1‰ in nature, is essential for paleoclimate, (eco) hydrology, and atmospheric science applications.
- Streamlined, simple, and simultaneous measurements of δ18O, δ17O, δ2H, and 17O-excess in liquids and vapor
- Average to <15 per meg precision on 17O-excess for 1-hour vapor measurements
- Repeat measurements demonstrate 15 per meg precision on 17O-excess for liquids
High-precision measurements of all three oxygen isotopes (16O, 18O, and 17O) was once limited to highly specialized labs with expensive, complex sample preparation systems for analysis by isotope ratio mass spectrometry (IRMS). The Picarro L2140-i analyzer delivers precisions of 15 per meg or better on 17O -excess at the touch of button. Introduce water directly into the analyzer, either as vapor or using a vaporization process that converts liquid water to vapor.
PICARRO L2140-i in Thailand
The PICARRO L2140-i is an isotopic water analyzer that measures δ18O, δ17O and δ2H at the same time, together with 17O-excess, and Thai Unique supplies and supports it for research laboratories in Thailand.

Where the isotopic water analyzer is used in Thailand
Based on the specifications above, the L2140-i suits laboratories that
- Need to measure δ18O, δ17O and δ2H simultaneously in liquid water or water vapor
- Work in paleoclimate, (eco)hydrology or atmospheric science, where natural 17O-excess deviations are typically below 0.1‰
- Want to introduce water vapor directly, with 17O-excess precision averaging below 15 per meg over 1-hour measurements
- Study present-day climate or the interactions between the hydrosphere and biosphere by pairing 17O-excess with high-precision δ18O and δ2H data

Frequently asked questions
Can the L2140-i measure liquid water samples as well as water vapor?
Yes. Water vapor can go directly into the analyzer, liquid samples are first turned into vapor, and repeat measurements of liquids have shown 15 per meg precision on 17O-excess. To discuss the setup for your own samples, please talk to our team.
Why buy PICARRO L2140-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 water 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.
