Electrochemical pre-concentration technique for use with inductively coupled plasma atomic-emission spectroscopy. Part II

Abstract

Two new electrochemical cells are described for the pre-concentration of trace elements from flowing solutions. The cells operate under controlled hydrodynamic conditions and are therefore suitable for in-line use with the nebuliser sample introduction system of the inductively coupled plasma. Their performances as pre-concentration cells are compared with the wall-jet cell described in Part I.
