Sample handling is an important aspect of any successful trace elemental analysis, with on-line procedures for sample preparation and delivery increasingly becoming methods of choice as the demands for productivity increase. Flow injection for atomic spectroscopy (FIAS) is a superb complement to PerkinElmer’s atomic absorption (AA) and inductively coupled plasma optical emission spectroscopy (ICP-OES) systems as a means of sample preparation and delivery. Fully integrated and automated systems, the FIAS 100/400 can dramatically increase the laboratory's productivity and capabilities.
