Carbonyl Sulfide Analyzer

To address exciting new opportunities for studying gross photosynthesis, LGR's OCS Analyzer (Carbonyl Sulfide or COS) simultaneously reports measurements of carbonyl sulfide (OCS or COS), carbon dioxide (CO2), carbon monoxide, and water vapor (H2O) in air continuously with extraordinary precision and sensitivity.

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.
