Picarro L2140-i Analyzer

The L2140-i triple water isotope analyzer measures δ18O, δD and water vapor concentration, as well as δ17O and determines the 17O excess.  

The abundance of the oxygen isotope 17O, as well as deviations from the ratio of δ17O and δ18O, represent valuable additional tracers that are increasingly used in isotope hydrology, climatology, and biochemistry. Until a few years ago, only isotope ratio mass spectrometry (IRMS) was an option for analysis due to the extremely high demands on measurement accuracy, but this was associated with high costs, complex sample preparation and low throughput.   

The L2140-i combines the advantages of CRDS laser spectroscopy with extremely high precision (<0.015 ‰ for 17O excess in water vapor) to meet research requirements.  

One analyzer. Multiple applications.

Picarro water isotope analyzers can work with many different types of samples from solids, liquids, and water vapor through specialized peripherals, whether dealing with high salinity, organic contaminants, or difficult calibration conditions in the field. Please feel free to contact us for advice on selecting a setup best suited to your project.
