Abstract
The optothermal window method, a variant of photoacoustic spectroscopy , was used at 10 mu m wavelength to explore its feasibility for direct investigation of aqueous solutions of lactose and corn tarch. Present limits of detection attainable by this method are 0.19% (w/w) for lac tose solution and 0.6% (w/w) for corn starch gel, respectively.
