Liquid water Isotopic analysers

The ABB LGR-ICOSTM GLA431 enhanced performance benchtop liquid water isotope analyser (LWIA) provides simultaneous and continuous measurements of delta-deuterium (δ2H) and delta-18-oxygen (δ18O) in fresh water, sea water, other liquids and discrete vapor samples with unsurpassed precision and speed, while the LWIA-24 also offers measurements for delta-17-oxygen (δ17O).

The LWIA range is ideal for a wide variety of hydrological, analytical and biological applications that involve measurements of fresh water, seawater, and other liquids. Gas isotopes measured by the ABB GLA431 series of Liquid Water Isotopic Analysers include delta-deuterium, delta-18-oxygen.

Their ease-of-use, field durability, and high throughput make them the industry standard and used by researchers, scientists, government agencies and intergovernmental organisations on all seven continents.
