【Abstract】 A high speed spectrophotometer based on a linear CCD was developed. The function and structure of the hardware and the software for the instrument were discusse d. The elementary performance was tested as follows: wavelength range 200-820 n m , full spectrum scan time <0.1 s, spectral bandwidth 0.7 nm, wavelength a ccuracy ±1 nm, photometric accuracy ±0.005 AU, baseline flatness <0.001 AU (rms), and stray light <0.1%. Results showed that this instrument is easy to use, fast and with high analytical performance. In addition, it has internet function of remote control and remote access. With the powerful data processing and spectrum analyzing software, it will provide a strong tool for routine analy sis and the research on dynamic reaction in chemistry and biology fields.更多还原
