Let's go🔥

I belong to a family of techniques, named as if the colourless do not belong.

I and the rest of the family constitute a general method for separating mixtures.

When any of us is in operation, there is always one kind of competition or the other among the constituents of the mixture being separated.

I, just like the others, have a stationary phase and a moving phase.

The competition or the race involves electrostatic or physical adsorption or partition.

In my case different ions in the mixture compete for ionic sites on the stationary phase.
