Microsampling techniques in laser raman spectroscopy

Laser sources for Raman spectroscopy make it possible for the chemist and spectroscopist to routinely and rapidly record the spectra of a fewμg of liquids and solids. Taking more care, as little as 0.5μg sample suffices to yield a good Raman spectra. The techniques for handling liquids, solids, and gas chromatographic fractions are described.
