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.
