Liquid Water Isotope Analyzers (LWIA)

LGR-ICOS™ Liquid Water Isotope Analyzer (LWIA) Solutions We Offer

We provide LGR-ICOS LWIAs that ensure fast and accurate measurement of δ2H, δ18O, δ17O and O17-excess in water and other fluids. = ABB’s models come with advanced post-analysis software that simplifies analyses and enhances performance. These instruments are used by researchers, scientists, governmental agencies and intergovernmental organizations. Here are the models of LGR-ICOS LWIAs we offer for a range of deviation measurements.

• LGR-ICOS™ GLA132-LWIA: This is an ultraportable analyzer for fast, field-based measurements of δ²H and δ¹⁸O isotopes. This model operates on DC power at an unmatched speed with 90 unknowns and 30 reference samples daily, which means six injections per sample. Ideal for hydrological, analytical, and biological applications that involve field measurements of fresh water, seawater, and other liquids, this model has an internal computer that can store data and send it to the data logger in real-time.
• LGR-ICOS™ GLA431-TLWIA: This is a triple analyzer for highly precise and speedy measurements of δ2H, δ18O, δ17O and O17- excess of water in liquid. This model is designed to incorporate excellent thermal control for ultra-stable measurements with unsurpassed precision, accuracy. and drift. It offers high-resolution absorption spectra that are continuously viewable for real-time diagnostics. OA-ICOS analyzers use a fourth-generation, cavity-enhanced absorption technique, have a rugged design, and are easy to operate. They are capable of performing unattended operations with automated injection of liquid samples.

Understanding Water Isotopes: A Hidden Dimension

Water isotopes refer to different water molecules of H2O that vary in atomic weights of hydrogen and oxygen atoms owing to varying neutrons in each. Hence, their masses differ. These isotopes are found in hydrogen, deuterium, and tritium, and oxygen - oxygen-16, oxygen-17, and oxygen-18. Finding out these differences with speed and precision enables scientists to understand different processes in ecological and paleoclimatic studies, oceanography, hydrology, biogeochemistry, and more.Studying the fractionation of water isotopes δ²H and δ¹⁸O is significant in environmental research. These isotopes can serve as key indicators of certain environmental changes based on how they fractionate through various natural processes such as evaporation or condensation. They help with information on past climate studies such as sediment records, cave deposits, ice cores, and so on as δ¹⁸O and δ²H values vary with temperature changes. Their fractionation due to precipitation can indicate factors such as altitude, distance above the seal level, and more. These isotopes are also helpful in studies about the human impact on hydrological cycle, atmospheric studies, and more.
