Use of absorption spectroscopy for determination of selected blood spectral characteristics

A dedicated absorption spectroscopic system was set up using tungsten-halogen broadband source, optical fibers, sample holder, and a commercial spectrometer with CCD array. The absorption spectra were measured for whole blood, separated components: plasma, saline, washed erythrocytes in saline and human whole blood with biomarkers (biocompability nanodiamonds). Blood derived from a number of healthy donors. Time of single measurement was about 1 sec. Data processing was applied to the absorption spectra to reduce spectral noise, and improve the quality of the spectra and to remove baseline level.
