Calculation of the deposition temperature in thermochromatography

For radiochemical analysis and identification of nuclear reaction products using thermochromatographic method by analysis of the basic equation of the ideal linear thermochromatography for columns with constant temperature gradient, there were deduced some approximate analytical formulae which discribe the dependence of the deposition temperature, TA (maximum of the thermochromatographic peak) on the enthalpy of adsorption, ΔHa0, and on experimental parameters, the dependence of the entropy of adsorption on temperature is allowed for. The formulae are valid within broad range of values of the variables, comparison with the numerical solution of the basic equation demonstrates, that their accuracy is better than that of experimental TA's. Formula for calculating ΔHa0 as a function of TA and the experimental conditions is obtained as well
