Spatial imaging of thin-layer chromatography plates using laser-induce
d fluorescence and surface-enhanced Raman scattering has been accompli
shed with a stationary two-dimensional Hadamard encoding mask. Detecti
on of three nanograms of pararosaniline hydrochloride on a thin-layer
chromatography plate was made possible by means of the surface-enhance
d Raman phenomenon. The imaging capabilities of the stationary two-dim
ensional Hadamard encoding mask coupled with the depth profiling abili
ty of photoacoustic detection allows for the three-dimensional photoac
oustic imaging of a multiple analyte sample.
