Measurement made easy
Overview
ABB’s Carbon Dioxide Isotope Analyzers meet all of these requirements. In addition, the availability of many value-added options extends the abilities of these units to include discrete samples (collected in bags or vials) and to automatically handle multiple inlet sources.
ABB’s “Enhanced Performance” series incorporates proprietary internal thermal control for ultra-stable measurements with unsurpassed precision, accuracy and drift. Moreover, only ABB’s analyzers provide reliable guaranteed measurements at mole fractions more than 20 times ambient levels.
ABB’s patented OA-ICOS technology, a fourth-generation cavity enhanced absorption technique, has many advantages over conventional Cavity Ringdown Spectroscopy (CRDS) techniques such as being alignment insensitive, having a much shorter measurement time, not requiring tight control of cavity pressure and temperature, and not requiring expensive and power-consuming auxiliary elements.
The analyzer includes an internal computer that can store data practically indefinitely on its internal hard drive (for applications requiring unattended longer term operation), and send real-time data to a data logger through its analog and digital (RS232) outputs. Several optional features are available which improve the flow time response, allow multiple inlet sources, or provide for remote access and control of the analyzer via the Internet.
