Abstract
Apparatus is disclosed for collecting and concentrating trace ions from a pressurized aqueous sample in a sample line. A three-way valve is connected to the sample line which in one position can divert the sample into a syringe and in another position can close off the sample line and permit the sample to flow from the syringe through the three-way valve into a concentrator column. In an alternative apparatus, the sample line is connected to a tee which permits the diversion of the sample into a concentrator column connected to the tee. The other end of the concentrator column is joined to a syringe for drawing the sample through the concentrator column. Methods of operating the apparatus are also disclosed.
