| Research Abstract |
A simultaneous imaging system of the temperature and concentration of aqueous solutions in microchannels was developed. The principle of this method is based on the temperature dependence of near-infrared absorption spectrum of water. The system acquires absorbance images at the temperature sensitive wavelength (1412 nm or 1905 nm) and at the isosbestic point (1442 nm or 1935 nm) alternately with 100 frames/s for each wavelength. The absorbance images of ethanol aqueous solutions with several conditions of temperature and concentration in the microchannels were obtained, and using these images at the two wavelengths, temperature and concentration images were constructed, which indicated the validity of the method. In the neutralization experiments, the concentration changes of the acid and base solutions by the reaction were successfully shown.
