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.
