ORION<sup>®</sup> CO2 & CH4


Increasingly, monitoring the variable levels of carbon dioxide and methane in relation to each other is of great interest in many research projects.  For those researching carbon capture and storage (CCS), a key challenge lies in monitoring the effectiveness of the storage solution. The main indicator of robustness is the flux of carbon dioxide (and its tracer, methane) from the ground. For scientists, monitoring changing levels of the two gases simultaneously can provide a deeper understanding of a dynamic environment.

MIRICO’s ORION® CO2+CH4 is an open path monitoring system ideally suited to measuring concentrations of both carbon dioxide and methane simultaneously in real time.

In adverse weather conditions that would significantly affect the accuracy and reliability of other monitoring systems, the ORION® delivers more reliable and highly sensitive measurements to provide greater confidence in the results.
