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.
