An oscillating mirror rapid scanning spectrometer Is demonstrated as a uv-visible detector for liquid chromatography. The spectrometer can scan the 200-930 nm spectral range at a scanning rate of up to 4.25 kHz with a repetition rate of up to 218 Hz. Three-dimensional chromatograms in which the 200-328 nm range was scanned each second during the separation of uracil, cytosine, and adenine were obtained. Recording complete spectra at short time intervals during the entire chromatogram provided qualitative Information about components as they eluted and enabled maximum sensitivity for all components by obtaining chromatographic data at the optimum wavelengths from the threedimensional chromatogram.
