The ultralight and compact SOF Xplorer is a novel instrument for emissions monitoring using the Solar Occultation Flux method (standardized according to EN17628). It’s based on a mid-infrared spectrometer equipped with a thermoelectrically cooled MCT detector. A custom rapid and sensitive solar tracker automatically directs the…
The instrument can be easily deployed on the roof of a car or mounted on a UAV platform. Geo-tagged measurement results are displayed in real-time to allow for efficient source screening and emissions monitoring. By combining the data with wind speed and direction the vertical column data (mg/m2 ) can be converted to gas mass fluxes (kg/h).
Note: The SOF Xplorer is available in two configuration, one tailored for optimal alkane detection (a) and another, multi-species version (b) for ammonia, alkenes and other gases.
