ABSTRACT:
Method of concentrating a low-concentration element in a solution and removing other, high-concentration elements, using an ion exchange resin specific to the element to be concentrated.
The resin is disposed in a mini-column less than 3 mm in diameter into which the solution is made to pass, the elution of the element from the resin is carried out by using a very small volume of elution liquid.
The invention applies to quantitative analysis by emission spectrum in an inductive plasma, and in this case the whole of the small volume of elution liquid, previously nebulized, is simultaneously supplied to the plasma.
