✦ Synopsis

A preliminary comparison of a new x-ray Ñuorescence (XRF) technique, grazing emission x-ray Ñuorescence (GEXRF), with several other XRF techniques is described, based on previous experiments and literature. These techniques are total reÑection XRF, conventional energy-dispersive XRF, wavelength-dispersive XRF and particleinduced x-ray emission. The comparison is done from a number of viewpoints, including preferred sample type and size, multi-element determination, interferences, accuracy, detection limits and cost of instruments. Di †erent analytical procedures for aqueous solutions between these techniques are indicated. Particular emphasis is placed on the position of the GEXRF technique, and it is indicated for what sample types and/or analytical problems GEXRF will o †er signiÐcant advantages over the other techniques.
