Product Description

 

 

Atomic Absorption Spectrophotometer with Graphite Furnace AA System AA500G

 


The AA500 Atomic Absorption Spectrometer is a high performance automated instrument designed to meet the requirements of the modern laboratory. Due to its versatility and performance it can be used for a wide range of applications. The versatile instrument is available in three configurations:

AA500G-The instrument is equipped with a graphite furnace atomizer only. The graphite head is fixed into the optical path to maximize performance and eliminate drift. The temperature of the transversely heated graphite tube is accurately controlled by means of a precision feedback system. Pyrolytically coated platform tubes are supplied as standard to improve the performance and eliminate many analytical problems associated with this technique.

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.
     



 

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)
