Optical device for quantification of volatile sulfur compounds involves measurement of absorption and reflectance

摘要

The optical device for quantification of volatile sulfur compounds involves the measurement of absorption and reflectance. It includes an optical sensor component sensitive to volatile sulfur compounds which in turn comprises an oxidation reduction colorimetric reactant sensitive to volatile sulfur compounds immobilized on a solid support. The sensor can be incorporated in a flow cell placed in the optical path of an instrument or alternatively in the common end of a bunch of optical fibers for remote detection. The optical changes produced in the sensor or interaction with the volatile sulfur compounds can be quantified by coupling the sensor to a UV/VISA detection system.
