Abstract

A dual-cathode glow discharge lamp was successfully applied to the determination of vanadium in commercial tool steels. A unique feature of our lamp is its capability to eliminate undesired argon emission signals. In the case of the vanadium determination, an analytical line, VI 437,92 nm overlaps with the Ar II 437.97 nm line. However, an interference-free detection of this line can be performed using the lamp, leading to accurate analyses of 0.1 - 2.5% vanadium in steel samples.
