Abstract
Preconcentration of volatile organo-mercury and metallic mercury on silver microcolumn is particularly suitable for the determination in air and water samples. The microcolumn is coupled to a cell for mercury determination by f.a.a.s. With this technique, down to 1 ng of mercury can be determined with a good precision (¶15%).
