We present the spectroscopic study of milk with soy and discuss using that for express-analysis. In the non-elastic light scattering spectra the luminescence band are found in visible region. A peak of the band is dramatic changed with changing soy concentration in milk. the nature of phenomenon is discussed. The obtained results can be used for instrumental express-analysis soy in milk by modified the laser device <MIG> have constructed for determining fat and protein in milk.
The theoretical and the experimental researches of spectra of absent-minded radiation in medium containing viruses were carried out. The information on spectra luminescence 31 viruses was written down.The new method the express - analysis of viruses in organism of the man was developed. It shall be mentioned that the proposed method of express diagnostics allows detection of infection agent in the organism several hours after infection. It makes it suitable for high
efficient testing in blood services for detection and rejection of potential donors infected with such viruses as hepatitis, herpes, Epstein-Barre, cytomegalovirus, and immunodeficiency. Methods of serum diagnostics used for that purpose can detect antibodies to virus only 1-3 months after the person has been infected. The device for the express analysis of 31 viruses of the man was created.
Experimental investigations of light scattering in milk polluted by salts of metals are presented. The phenomena of luminescence and quenching of luminescence by impurities are found. These results can be used for instrumental express analysis of toxins in milk by modified laser device 'MIG' which had been constructed for monitoring composition of milk. Application of laser for express diagnostic of toxins in liquid biological systems is discussed.
We present a new device called <> for monitoring milk parameters and discuss some possibilities of its modification for express-diagnostics of man-caused contamination. At present, the developed laser device <> is capable of precisely measuring the concentration of fats, proteins, and water in milk. The operation of the device is based on comparing the intensities of elastic scauering radiation from three semiconductor lasers with different wavelengths in the near-infrared range. It takes only about 30 seconds to complete a single measurement. Now we are developing a method for express-diagnostics of man-caused toxins (antibiotics, metal salts, etc.) in milk by studying non-elastic scattering and luminescence induced by visible-range laser radiation. The non-elastic scattering radiation in milk contaminated with a salt of lead is studied. It is observed that the radiation intensity decreases with an increase in the impurity concentration. We suppose that this is due to luminescence quenching caused by the impurity presence We have found out that the scattered light intensity exponentially changes with the concentration of the metal. The sensitivity in changing light intensity especially high at low concentrations of impurities. We suppose that these results can be used for express-diagnostics of toxins in milk by the proposed laser device <>.
