A process for preparing an ion-exchangeable media within a moving-bed or simulated moving-bed device, which can create a true or simulated media flow, comprising the steps of packing the bed with ion-exchangeable media and passing a solution, containing a mixture of ionic species, through the media, wherein the solution is passed partly or completely counter-current to the media flow direction such that the ionic species are loaded to a desired level upon equilibration.

Preparation of homogeneously loaded ion exchangers

An apparatus is provided for the detection of changes in concentrations or amounts of components of a fluid mixture by measuring changes in an electrical or a mechanical property of a sensing element when the sensing element is exposed to the fluid mixture. The preferred property of the sensing element to be measured is its electrical resistance which changes when the sensing element adsorbs at least one component of the fluid mixture.
