1. A system for use in in-situ analysis of pharmaceutical samples, said system comprising:
means for holding a plurality of said samples, wherein said samples are present in the form of a powder formulation;
means for moving said plurality of samples along a sample path;
means for generating a plurality of incident radiation pulses of different wavelength;
means for illuminating at least a respective one of said samples with at least a respective one of said radiation pulses during said movement of said samples, said radiation pulse having a suitable range of radiation wavelengths capable of inducing a fluorescent response;
means for detecting a first resultant fluorescence emitted from each of said samples;
first control means in communication with said moving means and said incident radiation generating means for synchronizing said means for illuminating each of said samples with said moving means.
