Water isotope analyzer (δ 2H, δ 17O, δ 18O, H2O)

For liquid water samples,IWACan measure δ synchronously at a faster speed²H,δ¹⁷OAnd δ¹⁸O, default program(For each sample)6 Repeated attempts can achieve110 An unknown sample/Heaven; For the measurement of water vapor isotopes,IWAcan2HzSimultaneously measuring the collection frequency of δ²H,δ¹⁷O,δ¹⁸Oas well asH₂OMolar fraction, upper limit of water vapor concentration measurementaccessible60000ppmUsers can achieve two measurement modes for liquid water and gaseous water with just one simple commandSwitching styles.IWAUsed itLGRTemperature control technology ensures smaller instrument drift and provides higher performanceAccuracy and precision.

Same as all othersLGRLike an analyzer,IWAReal time provision of high-resolution laser absorption spectra, enabling users toMaster and diagnose the performance of instruments; Equipped with a built-in computer（Linux OSReduce virus risk to a lower level),To provide functions such as continuous storage and measurement of data; Equipped with remote control function, users can access it through a web browserThe analyzer can be operated from any location, and real-time data sharing and instrument diagnosis can also be performed through remote login.IWAContains advanced data post-processing software that automatically executes analysis programs for liquid water measurement, replacing the previous oneThe extensive manual work required by researchers after data collection; Capable of automatically performing data analysis and calibration functions,Display measurement results graphically and diagnose the operational status of the diagnostic instrument. The post-processing software also includesLGRSpectral pollutionDiagnostic technology（SCI）By analyzing high-resolution absorption spectra in detail, it is possible to check, quantify, and correct the presence of impurities in water samplesInterference from organic pollutants.
