摘要：
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, V I 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.
