摘要：

A powerful and compact experimental arrangement for simultaneous multi-element measurement by laser induced fluorescence is presented. The analytes are excited in a commercial graphite furnace atomizer by cw semiconductor diode lasers and the fluorescence is detected by a simple photodiode without interference filters or a polychromator. In preliminary measurements, detection limits of 1 pg ml-1 (10 fg absolute) and 2 pg ml-1 (20 fg) for lithium and rubidium, respectively, have been obtained.
