L2130-i Isotope and Gas Concentration Analyzer
Measures δ18O and δ2H for Isotopic H2O
CONTACT US
The Picarro L2130-i isotope analyzer provides high quality measurements of water stable isotopes for demanding applications such as paleoclimatology, hydrology, and oceanography. δ18O and δ2H high-precision measurements can be made with water samples from liquids, vapor, and solids, using a variety of Picarro peripherals.
- High-precision measurements of δ18O and δ2H
- Minimal drift: calibrate once per day while measuring with sub per mil certainty
- Flexibility to measure water samples from liquids, vapor, and solids
- Small footprint, robust design, and intuitive user-interface
Precision with a liquid sample is guaranteed to be 0.025/0.1‰ for δ18O/δ2H, and drift, over 24 hours, is guaranteed to be 0.2/0.8‰ for δ18O/δ2H. Vapor specifications include a measurement range from 1,000 to 50,000 ppm, with guaranteed precision at 2,500 ppm of 0.250/0.080‰ for δ18O (for 10/100 seconds) and 1.600/0.500‰ for δ2H (for 10/100 seconds), and guaranteed precision at 12,500 ppm of 0.120/0.040‰ for δ18O (for 10/100 seconds) and 0.300/0.100‰ for δ2H (for 10/100 seconds).
New Measurement Modes on L2130-i and L2140-i Analyzer Offers Higher Throughput
New 'Express mode' will allow measurements of up to 50 samples per day while maintaining excellent precision.
The new 'Survey mode' will allow measurements of up to 150 samples per day. Table 1 preliminarily compares the performance of the existing modes with our new methodologies for increased throughput.

| Mode | Injection volume (µL) | Measurement time (min) | Samples/day | δ¹⁸O precision [%] | δ2H precision [%] |
|---|---|---|---|---|---|
| Current specifications | 1.8 | 54 | 27 | 0.025 | 0.1 |
| Standard mode | 1.8 | 54 | 27 | 0.01 | 0.05 |
| Express mode | 1.8 | 28 | 50 | 0.01 | 0.05 |
| Survey mode | 2.5 | 9.5 | 150 | 0.05 | 0.11 |

Measures δ18O, δ17O, and δ2H and determines 17O-excess
CONTACT US
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.
