摘要
A repeat-scanning spectrophotometer was designed to scan the 200-800 nm spectral range in 375 ms with a repetition rate of 2 Hz, or in 750 ms with a repetition rate of 1 Hz. The flow cell used for chromatographic experiment had a sample path of 10 mm and a volume of 8 μL- The spectrophotometer was interfaced to a small computer to perform multiwavelength detection. The simultaneous recording of chromatograms at different monitoring wavelengths, and instantaneous recording of absorption spectra were performed. The capability of multiwavelength detection has been demonstrated with an experiment on the gel chromatography of benzoylacetone and its Be(II) and Cr(III) chelates. © 1979, American Chemical Society.
