Optical Sensing (VIDEO) Chalmers University of Technology This video is under embargo. Please login to access this video.

This gives an initial rough indication that a vessel is releasing too much sulphur; the results must then be confirmed with a physical/chemical analysis. The vessel in the film is not breaking the rules, because the recording was made before the sulphur regulations were tightened.
