Fully Automated Single Beam Flame & Graphite Atomic Absorption Spectrophotometer AA500FG


Features & Functions

AA-Win Pro software provides full control of the instrument and auto sampler with easy method change for each technique
Automatic 8 Hollow Cathode lamp turret controlled and optimized by the AA-Win Pro software. Operating lamp current and warm-up current can be individually controlled to eliminate drift commonly associated with lamp warming
D2 lamp background correction system fitted as standard to all configurations. High energy D2 lamp and adjustable beam splitter mirror are optimized by the AA-Win Pro software
Self reversal background correction system fitted as standard to all configurations. The high performance background system uses the same hollow cathode lamp as installed for the analysis. Minimum extra components are required and optical alignment is very simple. Self reversal can be used for any element at any wavelength making it extremely versatile.
High precision minimal optics ensures maximum light throughput to the computer controlled Czerny-Turner monochromator.
A universal auto sampler is available as an optional accessory which is conveniently mounted on the front of the AA500 instrument.
Absorption and Emission modes are standard features in the AA-Win Pro software as well as peak height, peak area, sequential and manual integration modes.


Flame Atomiser Features

The flame atomizer offers three flame options: Air/Acetylene is the standard configuration with the N2O/acetylene and Air/LPG as options.

Air/Acetylene
The Air/Acetylene flame uses a 100mm single slot burner for the standard configuration
The high sensitivity (Cu 2ppm>0.280Abs) is due to the efficiency of the fixed position glass nebulizer fitted as standard. An acid resistant replacement is available as an option.
The flame can be easily set from blue lean flame through stoichiometric to fuel rich by means of computer control


N2O/Acetylene
The N2O/Acetylene flame uses a 50mm single slot burner and is available as an optional extra.
This flame configuration is used to measure elements less prone to ionization such as Aluminum, Tin, Titanium, Calcium, Vanadium and Molybdenum.
Switching from Air/Acetylene to N2O/Acetylene to Flame Off is fully controlled by the AAWin Pro software



Air/Propane (LPG)

This flame uses a 3 slot burner and with the low pressure requirement it is also much safer to operate
Due to the low temperature of the flame it is ideal for analyzing alkali metals such as Potassium, Sodium and Lithium, especially when used in the emission mode.
Some remote areas of the world have difficulty obtaining Acetylene gas of a high enough purity to operate the flame correctly. LPG can give a real alternative and offer comparable results for most elements throughout the wavelength range.



Safety Features

  • Pressure monitoring for all gases
  • Burner identification
  • Flame sensor
  • Drain trap level sensor
  • Gas leak detector
  • Over pressure in premix
  • Safety cut off switch


Graphite Atomiser Features

The integrated Graphite Furnace Atomiser is available in two instrument configurations.

  • In the AA500G instrument the graphite furnace head is fixed into the light path so alignment with the optical path is simple and accurate
  • In the AA500FG instrument the graphite furnace head is fixed behind the flame atomizer assembly and is motorized into position by a simple operation in the AAWin Pro software. The positions for the flame and graphite are saved making it easy to swap between modes for different analysis
  • The temperature of the transversely heated graphite tube is accurately controlled by means of a precision feedback system and has been designed to reduce analytical problems normally associated with this type of technique.
  • Pyrolytically coated graphite tubes are used as standard and are manufactured to improve performance as well as increase the analytical life
  • Platform graphite tubes are supplied as standard and will accept volumes up to 20μl. Non-platform graphite tubes are also available as an optional extra
  • Up to 10 heat stages are available for the programming of the graphite atomizer. These can be set and stored within the AAWin Pro software
  • The graphite tube is held in position by means of a gas piston. Replacement of the graphite tube is performed by a simple command in the AAWin Pro software.
  • The graphite tube is efficiently cooled by an additional water circulation system (supplied separately)
