Determination of medium concentration urea in solution by p-dimethylaminobenzaldehyde colorimetry;

Research on Determining the Polysaccharides Content in Capsella bursa-pastoris by 3,5-Dinitrosalicylic Acid Colorimetry

The Propericitate Wavelergths Determination of the Recombination Human Granulocyte-Macrophage Colony Stimulating Factor by Colorimetric Determination;

The colorimetric fiber-optic pyrometer based on DSP chip-TMS320F2812has been designed for the need of high temperature measurement in industry.

Based on image processing,an improved colorimetric method to derive the temperature and emissivity images from a color CCD image for particle-laden combustion process is presented in this paper,which is independent of the spectroscopic characteristics and the representative wavelength of the CCD and the image processing system.
