摘要：

Noble metals such as iridium as well as certain other metals may be sputtered onto the inner graphite surface of a graphite tube for use as atomization surface in electrothermal atomization atomic absorption spectrometry. This is accomplished by a low pressure argon discharge process described earlier. It has also been shown previously that the use of such tubes may reduce background absorption when determining lead, cadmuim and selenium in a complex matrix such as whole blood.
