We propose our optoelectronic devices for mid-infrared spectral range
as a new powerful base for optical absorption analysis.
One of the great advantages of this method is that virtually any sample in virtually
any state may be studied. Liquids, solutions, pastes, powders, films, fibers, gases
and surfaces can all be examined with a proper choice of sampling technique.
This approach may be used for the analysis of one component in a mixture, especially when the compounds
in the mixture are alike chemically or have very similar physical properties.
Most of commercially available instruments for this analysis
employ quite sophisticated large-sized and expensive spectrometers that provide
measurements solely at the laboratory. Using IBSG LED-Photodiode optopairs for mid-infrared
spectral range allow developing portable sensors with high reliability and adequate accuracy
that can be successfully applied in different areas for matter analysis purposes. |
