- Abstract:
- Spectroscopic methods have been for years widely used in analytical laboratories. However, their application in industrial and environmental practice has been up to now relatively limited because of the high costs of spectrometric instrumentation. This is only recently that the advances of micro- and optoelectronics have made feasible integrated implementation of some spectrometric techniques and the design of low-cost spectrometers for industrial applications. The integration implies a significant reduction of instruments precision – mainly due to miniaturisation. This loss, however, may be partially compensated for by digital signal processing of raw spectrometric data. An algorithmic basis for a low-cost computer-assisted spectrometric system – that can be effectively used for qualitative and quantitative analyses of multicomponent chemical substances – is proposed in this paper.
