Product Details
The GW-2082CH ultra-high precision liquid water and water vapor isotope analyzer uses cavity ring down spectroscopy (CRDS) technology to synchronously measure δ with high precision18With δ D, this instrument has high stability, sensitivity, and accuracy. The gasification device is equipped with temperature control, and the scientific engineering design ensures that the instrument can directly measure high salt samples, such as brine. A high-precision temperature and pressure control system ensures that the instrument achieves the highest accuracy, precision, and low drift under constantly changing environmental conditions.
Water gas interface carbon dioxide flux analyzerIt is a tool for isotope research in multiple fields such as oceanography, hydrology, plant physiology, life sciences, paleoclimatology, atmospheric science, food science, agriculture, and mining science. The compact design makes it easy for you to apply in various environments such as field stations, shipborne vehicles, and laboratories.
Water gas interface carbon dioxide flux analyzerProduct Features
Synchronous measurement of δ18O and δ D, and can simultaneously output CH4 concentration.
Typical accuracy of liquid water, δ18O reaches 0.01 ‰; The δ D reaches 0.03 ‰.
A device for isotope measurement of solid water, liquid water, and gaseous water, with laboratory accuracy and field durability.
It has a fast response time for water vapor measurement, with 10 seconds per megagram (0.001 ‰) Allen variance.
Not sensitive to changes in environmental temperature, with minimal memory effect and drift.
Equipped with a miniature high-temperature pyrolysis module, it effectively removes the interference of organic matter on laser spectra.
