Overview

Measurement of δ 18O and δ D isotopes of H2O

Product Details

The Picarro L2130-i isotope analyzer can achieve high-quality measurement of water stable isotopes, suitable for harsh applications such as paleoclimatology, hydrology, and oceanography. By using various Picarro peripheral devices, high-precision measurements of δ 18O and δ D can be performed on water samples taken from liquids, gases, and solids.

High precision measurement of δ 18O and δ D
Minimum drift: Calibrate once a day while achieving sub ppm accuracy measurement
Flexible measurement of water samples taken from liquids, gases, and solids
Small footprint, sturdy and durable design, intuitive user interface

For δ 18O/δ D, ensure that the accuracy of the liquid sample is 0.025/0.1 ‰ and the drift within 24 hours is 0.2/0.8 ‰. The water vapor measurement specifications include a measurement range of 1000 to 50000 ppm; For δ 18O (10/100 seconds) and δ D (10/100 seconds), ensure that the accuracy at 2500 ppm is 0.250/0.080 ‰ and 1.600/0.500 ‰, respectively, and the accuracy at 12500 ppm is 0.120/0.040 ‰ and 0.300/0.100 ‰, respectively.
