A multipurpose UV-visible spectroscopic system

摘要

The complex is intended for recording the spectral responses of the UV-visible radiation in various analysis modes (absorption and emission spectrophotometry, spectrofluorometry, and Raman spectroscopy), as well as scanning modes (excitation and luminescence wavelengths, and synchronous one). The open architecture of the automation hardware and software allows one to flexibly change the complex configuration and operation mode and to expand the range and composition of spectral devices. The amplifier-converter with a low level of input current noise (1.5 fA in a range of 0-1 Hz) provides photocurrent recording in the ii 6-dB dynamic range.
