The analyzer is simple to use, low power and rugged which makes it ideal for a wide variety of field and air quality studies. The ability of the analyzer to simultaneously measure all three gases at high speed and over a wide range of mole fractions makes it an excellent choice for plant respiration and chamber flux measurements. In addition, the instrument automatically reports all gases on a dry mole basis (accurately corrects for water vapor dilution and absorption line broadening effects) by analyzing fully resolved high resolution lineshape measurements without any need for sample drying or post processing.
Only LGR’s analyzers provide reliable measurements at concentrations more than 20 times greater than typical ambient levels (to 8000 ppm carbon dioxide, to 10 ppm carbon monoxide in air).
LGR’s new “Enhanced Performance” series incorporates proprietary internal thermal control for ultra-stable measurements with unsurpassed precision, accuracy and drift. Moreover, only LGR’s analyzers provide reliable guaranteed measurements at mole fractions more than 20 times ambient levels.
For applications requiring highly mobile measurements in the field, LGR offers the COS Analyzer in our acclaimed portable package.
The Analyzer uses LGR’s patented Off-axis ICOS technology, a fourth-generation cavity enhanced laser absorption technique. Off-axis ICOS has many advantages over conventional optical techniques (including first generation cavity ringdown spectroscopy) such as being simpler to build, more rugged and alignment insensitive, having a much shorter measurement time, and providing measurements over a much wider dynamic range.
