[Experimental testing of micro biochemical analytical system].

A micro biochemical analytical system based on a micro fiber spectrometer is introduced. Experiment was carried out to calibrate and test the analysis system. In the experiment, the absorption spectra of Fe2+ -ferroin solution bodies with different concentrations were obtained. The working curve shows a fine linearity of the analysis system. The authors also compared the experimental results obtained from 722-spectrometer and those from our analysis system. It was shown that their system can meet the requirement of practical use. This system also has many advantages, such as real-time whole spectrum analyzing and small volume, and is an ideal instrument for biochemical analysis.
