As AND Se HYDRIDE TRAPPING AT THE QUARTZ SURFACE - A STEP FORWARD TO IN-SITU TRAPPING IN QUARTZ TUBE ATOMIZERS FOR AAS

Abstract

An optimization study of arsine and selenum hydride preconcentration at the quartz surface is presented. A novel apparatus design consisting of a quartz trap integrated with a quartz multiatomizer is described.
