Apparatus for flameless atomization of a sample for atomic absorption analysis

摘要

The present invention is directed to apparatus for flameless atomization of a sample for atomic absorption analysis, which includes a sample tube of electrically conductive material having a transverse bore offset axially towards one end of the tube with respect to the transverse central plane, an electrode arrangement including portions in electrical contact with the sample tube at spaced locations for passing an electrical current through the tube to cause heating thereof, and a system for generating an inert gas flow inwardly from the opposite end of the sample tube and outwardly through the transverse bore.
