# Determination of Bismuth in Cosmetics by HG-AFS

Bismuth compounds are often used in cosmetics as a replacement for lead given its toxicity. Bismuth can be measured by Aurora's hydride generation atomic fluorescence spectrometer, the LUMINA^TM 3300. The sample preparation consists of oxidizing Bi to Bi^3+, which reacted with BABH~4 yields BiH~3. The BiH~3 is moved to the atomizer by the courier gas and broken down there. The ground state of Bi can be excited by the light by the Bi-HC lamp and the fluorescence sign is measured consequently by photo multiple tube.
