Abstract

It is necessary for a modern spectrophotometry system to possess such properties as high measuring accuracy, fast working speed, uniform spectral response in the whole wavelength band, low consumption of power, little heat accruing while working, small size and low weight, etc. To meet all these needs, a spectrophotometry system today usually employs the so-called dual-beam channel configuration in which one sampling channel with another compensatory channel and a cold light source such as a xenon flash lamp, which usually causes an increase of the complexity in the system configurations. To further simplify the instrument configuration, we put forward a new dual-channel compensatory model called the integral compensatory model. Our experimental results show that using this new model, a spectrophotometry system cannot only be greatly simplified in its hardware but can also achieve highly accurate measurements.
