Abstract

A compact absorption spectrometer with a midinfrared tunable quantum cascade laser operating at 4.86 μm (2054 cm^-1) is used to measure lower concentrations of carbonyl sulfide (COS) in air. A detection sensitivity of ∼30 parts in 10⁹ of COS and the selectivity of two stable isotopes, ¹²C¹⁶O³²S and ¹²C ¹⁶O³⁴S, are demonstrated. Specifically, the feasibility of detecting COS in expired human breath as a potential noninvasive medical diagnostic tool is investigated.
