Preferred Label : sorption techniques;
Detailed label : sorption techniques in trace analysis;
IUPAC definition : Techniques based on the distribution of components being separated between two phases,
one of which is stationary and the other mobile. The advantage of some chromatographic
methods is the possibility of combining the preconcentration and determination steps,
as well as improving the speed of determination, and the possibility of separation
of components with similar properties, and of achieving high values of the preconcentration
coefficient. The methods enable analyses of microamounts of substances. ion-exchange
chromatography is not widely used owing to the great volumes of solutions being treated
and, consequently, to a great degree to the variation in the blank, and to some diffusional
limitations. Static ion-exchange, which is much simpler and more readily carried out,
is practised quite widely.;
