Atomic Absorption Spectrophotometer

  Home / Products / Spectrophotometer

The AA8000 Atomic Absorption Spectrophotometer is double beam with sealed and vibration free optical system, having Czerny-turner Monochromator with Holographic with Holographic grating (1800lines/mm). It’s 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 including: Agriculture, Soil, Environmental, Food, Metal, Mining, Petrochemical, Clinical, Pharmaceuticals.

The Instrument is available in three configurations :
AA8000F - The Instrument is equipped with a Flame atomiser only. 3 flames are available with the air/ acetylene as standard configuration and N2O/acetylene or air /LPG (natural gas) available as an option. All 3 flame configurations offer coded burner for full safety protection.
AA8000G - The instrument is equipped with a Graphite Furnace Atomiser only. The Graphite head is fixed in to the optical path to maximise performance and eliminate drift. The transversally heated graphite tube is efficiently heated and cooled due to the precision feedback system.
AA8000G - The Instrument is equipped with both Flame and Graphite Furnace Atomiser’s as detailed in the previous description. Both configurations are installed into the instrument and can be changed over by a simple selection in the versatile AA-Win software.
Salient Features :

GLP compliant software is now available for all AA8000 Configuration.
D2 Lamp or Self reversal background systems.
High precision minimal optics ensures maximum light throughput to the computer controlled Czerny – Turner monochromator.
High sensitivity absorbance better than 0.9abs for 5ppm Cu
A universal autosampler is available which can be used for flame as well as graphite furnace system with Auto Dilution facility.
Absorption and Emission modes are standards as well as peak height, peak area, sequential and manual integration modes.
Autoflame Ignition. Nebulizer Interlock for gas leakage etc.
New upgrade available with full Automation for Multi- Element Analysis.
Spray chambers chemically inert material capable of handling all corrosive materials.
Flame Atomiser Features
  3 flame systems are available. Air/ acetylene is the standard configuration with the N2O/acetylene and Air / LPG as options.
Air / Acetylene
* This flame uses a 100mm single slot burner for standard configuration.
* The high sensitivity (Cu 5ppm>0.9A) is due to the efficiency of the fixed position High Efficiency Nebuliser fired as standards. An acid resistant replacement is available as an option.
* The burner for this gas has a 50mm slot and is used to measure elements less prone to ionization such as : Aluminium. Tin, Titanium, Calcium and Vanadium.
* The switchover from air/ acetylene and flame off is fully computer controlled.
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 lower temperature it is ideal for analyzing alkali metals such as Potassium, Sodium and Lithium, especially when used in the Emission mode.
* There are some remote areas in the world that have difficulty obtaining acetylene or even a high enough purity to operate the flame, so LPG can.
