ANALYSIS OF ERRORS OF MEASUREMENT CHROMATOGRAPHIC METHODS

S.Р. Yarmolenko

Chromatographic methods of analysis based on various physical and chemical processes that make it possible to solve complex analytical problems of separation and the following definition of low concentrations of similar chemical properties. These analytical problems other methods to solve difficult and often - it is simply impossible. To solve this problem, you should not only improve gas chromatographs and their software is not only to control the chromatographic process, and result processing. Satisfactory description of the chromatographic separation of substances can be obtained by combining some of the theory of equivalent plates diffuse Van Deyemtera theory. To improve the reliability of such dimensions, but misses, make two or three observations, and the results of measurements taken arithmetic mean of the results of these observations.

Key words: diffusion, sorbent-sorbate, mobile - real phase factor, theoretical plate column chromatography, adsorption chromatography, linear and nonlinear chromatography, measurement error, confidence limit.
