Combined Flame and Graphite Furnace System PG990FG Atomic Absorption Spectrophotometer

Features & Functions

The flame and graphite furnace is integrated into one instrument.The change over from one technique to another is carried out by simple keystrokes within the software. The instrument has a motorized 8 hollow cathode lamp turret which allows the automatic positioning and optimization of each hollow cathode lamp by the software. The control of the gas flows for the fuel gas (C2H2) of the burner is also carried out directly from the software thus allowing optimization of the instrument for the analytical parameters for a selected analysis Two methods of background correction are available. The first utilizes a Deuterium Arc lamp and the second is the proven method of Self Reversal. High precision minimal optics ensures maximum light throughput to the computer controlled Czerny-Turner Monochromator.
