The analyzer uses ABB’s patented Off-axis ICOS technology, a fourth-generation cavity enhanced absorption technique which employs a high-finesse optical cavity as the measurement cell.ABB’s technology has many proven advantages over conventional first-generation cavity ringdown spectroscopy (CRDS) techniques. In brief, since the laser beam does not have to be resonantly coupled to the measurement cell (i.e. precise beam alignment is not critical), ABB analyzers are inherently robust thermally and mechanically. In addition, since ABB’s technology can record reliable absorption spectra over a far wider range of optical depths (absorbance values) compared with CRDS, ABB analyzers provide measurements over a much wider range of mole fractions (gas concentrations). Finally, due to the ease and simplicity of recording and quantifying the measured spectra, ABB analyzers display the entire absorption spectra to the user in real time allowing for immediate system diagnostics and performance validation.
The analyzer has an internal computer that can store data practically indefinitely on its hard disk drive and send real time data to a data logger via the digital (RS232) or Ethernet outputs. Furthermore, this analyzer may be controlled remotely via the Internet. This capability allows the user to operate the analyzer using a web browser practically anywhere Internet access is available. This remote access allows bios-level control of the instrument and provides the opportunity to obtain data and to diagnose the instrument operation without being on site.
ABB's "Enhanced Performance" series incorporates proprietary internal thermal control for ultra-stable, minimal-drift measurements with unsurpassed precision and accuracy.
