ANALYSIS OF ERRORS OF MEASUREMENT CHROMATOGRAPHIC
METHODS

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.
