Abstract

The literature documents a succession of individual improvements over previous graphite furnace technology. These individual improvements include graphite tubes with better pyrolytic coatings, Zeeman background correction, rapid heating of the graphite tube, the L'vov platform, faster instrumental electronics, and matrix modification. Any one of these developments will improve certain analyses. However, taken together as an integrated system, the total is more than equal to the sum of the parts. The integrated system, known as the stabilized temperature platform furnace technique, provides the analyst with capabilities not available on previous graphite furnace systems. Analyses are conducted differently, methods are developed differently, and the results are more predictable.
