OA-ICOS™ GLA431-TIWA Triple Isotopic Water Analyzer

Features & Benefits

• Both isotopic liquid water and water vapor measurements

• Reports δ²H, δ¹⁷O, δ¹⁸O, d-excess, ¹⁷O-excess (and H₂O in vapor mode) in real time

• High Throughput and High Performance modes in one system

• Switch between liquid and vapor measurements in seconds

• Highest accuracy water vapor

• Isotopic water vapor reported at high and low mole fractions

• Fast time response allows isotopic water vapor flux studies

• Enhanced Performance series provides unsurpassed stability and lowest drift

• Widest temperature range: 0 - 45 °C

ABB’s Enhanced Performance (EP) series incorporate proprietary internal thermal control for ultra-stable measurements with essentially no drift, unsurpassed precision and highest accuracy.

As with all ABB analyzers, the GLA431-TIWA provides users with the entire fully resolved absorption spectra for comprehensive performance validation and diagnostics in real time. Similarly, the analyzer has an internal computer (Linux OS) that can store data practically indefinitely on an internal hard disk drive and send real time data to a data logger via the digital (RS232) or Ethernet outputs.

The Analyzer includes advanced post-processor software which provides many features that increase user productivity, decrease data processing time, and provide data and system diagnostics. The ABB software offers a seamless interface with LIMS for Light Stable Isotopes for one-stop reference normalization, sample data storage, and client management.

ABB’s Post Analysis Software automatically performs many analysis procedures on liquid measurements that were previously done by researchers after the data was collected. Among the capabilities of ABB’s software package are to automatically apply calibration standard measurements made during the sample run, to graphically display all results, and to diagnose instrument operation. Moreover, the Post Analysis Software includes ABB’s proprietary Spectral Contamination Identifier (SCI) technology, which detects, accurately quantifies, and can correct for the presence of contaminants in water samples based on a detailed analysis of the measured high-resolution absorption spectra.

ABB analyzers may be controlled remotely via the Internet. This capability allows users to operate the Analyzer using a web browser anywhere internet access is available. Furthermore, remote access provides the opportunity to obtain and share data and to diagnose the instrument operation without being on site.
