PG990F Atomic Absorption Spectrophotometer with Czerny-Turner Monochromator
The PG990 Atomic Absorption Spectrometer is a versatile entry level instrument with a computer controlled Air/Acetylene flame for general laboratory requirements. Due to its high sensitivity and excellent performance the instrument can be used for a wide range of applications
Features & Functions
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.
The location of the wavelength and peak selection is automatically controlled from the software
The spectral bandwidth is automated and is available with a choice of five slit sizes
The electronic parameters for the photomultiplier tube detector, the hollow cathode lamp current and the balancing of the absorbance and background energies are controlled from the software
The ignition of the flame is computer controlled and the various safety interlocks offer a very safe operating system

The flame conditions are continuously monitored and should the flow rates change, an audible alarm sounds
The pressure of the support gas (oxidant) is monitored constantly. If the pressure changes then the flow of the fuel gas will be stopped and the flame will be safely extinguished
A sensor monitors the level of liquid in the drain and will prevent ignition if too low. The flame will also be extinguished if the level of liquid in the drain changes significantly.
A flame sensor monitors the flame and safely turns off the gas flow to the burner if the flame suddenly extinguishes.
The burner is identified by a switch making it impossible to light without the burner being fitted
An emergency flame off button is installed in case a problem is observed. The flame can be extinguished safely.
