ES                                            Atomic Absorption Spectrophotometer




         ATOMIC ABSORPTION SPECTROPHOTOMETER

         ATOMIC ABSORPTION SPECTROPHOTOMETER
         An entry level Flame Atomic Absorption Spectrophotometer. Features:
         Motorised 8 hollow cathode lamp (HCL) turret for automatic positioning and
         optimisation of each HCL by the software;
         Automatic fuel gas (C H ) flow rate adjustment to optimise combustion in
                          2 2
         element analysis;
         Automatic adjustment of burner height or optimised analysis conditions;
         Automated wavelength scanning and peak searching;
         Two background correction methods, the first utilises a deuterium lamp, the
         second is self­reversal;
         Automatic switchover of spectral bandwidths (5 choices);
         Automatic MPT and Lamp current adjustment, automatic AA and BG energy
         balance.
