Abstract
A sample is fed to an ICP-AES by applying suction to a mouth of the sample vessel extending into the central or inner capillary tube of the burner from an annular orifice or a plurality of spaced apart orifices. The amount of sample material is controlled by volume flow control or gas pressure control. The sample is in the form of a powder or vapor without dilution or entrainment of chemical contaminants.
