Abstract

A new optical method to seed a flow with elemental metal species is described and demonstrated using laser ablation. The unique ablation seeding approach is shown to generate free gas-phase metals in their atomic form, without the need for a spray or solvent. The technique can be used in both reactive and non-reactive environments, which solves a problem that has hitherto plagued the seeding of many flows. The ablative seeding approach has the potential to become a standard tool for chemical seeding, with a diverse range of application from flow tracing to atomic absorption spectroscopy (AAS). © Springer-Verlag 2012.
