AN039: Optimize the Precision and Accuracy of Seawater and High-Saline Water Stable Isotope Measurements

The Picarro Salt Liner is an easy-to-use, inexpensive accessory that protects the isotopic analyzer system from salt build-up in the vaporizer. It can be removed, cleaned, and replaced in a few minutes to reduce downtime. Picarro recommends cleaning and replacing the salt liner after every 24 hours of seawater analysis

Abstract: 

Applications in the fields of hydrology and oceanography require precise, accurate measurement of stable water isotopes, δ18O and δ2H, in seawater and high-saline water. Cavity ring-down spectroscopy (CRDS) analyzers produce high-precision measurements of water isotopes in gas phase. High levels of total dissolved solids (TDS) in water samples can foul laserbased spectroscopy analyzers and peripherals, adversely affecting performance and requiring frequent cleaning with extended downtime. The Picarro Salt Liner is an easy-to-use, inexpensive accessory that protects the isotopic analyzer system from salt build-up in the vaporizer. It can be removed, cleaned, and replaced in a few minutes to reduce downtime. Picarro recommends cleaning and replacing the salt liner after every 24 hours of seawater analysis
