Paper Abstract

We have performed pulsed photothermal radiometric measurements of thermal diffusivity of silica-gel on thin- layer chromatography plates at two different IR wavelength regions ane obtained values in the region of D equals 0.2 mm2/s. We then proceeded to depth profiling of TLC plates with photoacoustic measurements with modulated excitation using IR and visible excitation.
