         ATOMIC ABSORPTION SPECTROPHOTOMETER
         (AA500FPC/AA500GPC/AA500FGPC)
         Atomic Absorption spectrophotometer, fully automated system. Available in a
         choice of three configurations; Flame only, Graphite Furnace or Combined Flame
         and Graphite Furnace. The change over from one technique to another is via a
         simple key stroke within the software. All configurations have a built-in PC system
         complete with pre-loaded Microsoft operating system and AAWinPro Software. The
         Flame and Combined Flame and Graphite Furnace models have a data coded
         Air/Acetylene burner included.
         Features:
         Motorised 8 hollow cathode lamp (HCL) turret for automatic positioning and
         optimisation of each HCL by the software;
         Automatic switchover of spectral bandwidths (5 choices);
         Advanced Graphite Furnace Horizontally heated platform graphite tube;
         Computer controlled heating programmes which enables the user to select the best
         programme for the analysis;
         The optical temperature during atomisation stage ensures rapid heating and
         analysis.
