Complete Product Description

The PG Instruments 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 including: Agriculture, Clinical, Environmental, Food, Metal, Mining and Petrochemical.

The PG Instruments AA500 Atomic Absorption Spectrometer is available in three configurations:

• PG Instruments AA500F Atomic Absorption Spectrometer
  - The PG Instruments AA500F Atomic Absorption Spectrometer is equipped with a Flame atomizer 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.
• PG Instruments AA500G Atomic Absorption Spectrometer
  - The PG Instruments AA500G Atomic Absorption Spectrometer is equipped with a Graphite Furnace Atomizer only. The Graphite head is fixed into the optical path to maximize performance and eliminate drift. The transversally heated graphite tube is efficiently heated and cooled due to the precision feedback system.
• PG Instruments AA500FG Atomic Absorption Spectrometer
  - The PG Instruments AA500FG Atomic Absorption Spectrometer is equipped with both Flame and Graphite Furnace Atomizer'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.

• Embedded PC system built into the instrument as standard. Windows 7 professional operating system.
• Full software control of the instrument and autosampler.
• Pre-installed AA-Win software.
• Automatic 8 lamp turret controlled and optimized by the AA-Win software.
• D2 lamp and Self reversal background systems fitted as standard.
• High precision minimal optics ensures maximum light throughput to the computer controlled Czerny-Turner monochromator.
• A universal autosampler is available which is conveniently mounted to the front of instrument.
• Absorption and Emission modes are standard as well as peak height, peak

• Air/Acetylene
  - This flame uses a 100mm single slot burner for standard configuration.
  - The high sensitivity (Cu 2ppm > 0.28A) is due to the efficiency of the fixed position glass nebulizer fitted as standard. An acid resistant replacement is available as an option.
• N2O/Acetylene
  -The burner for this gas has a 50mm slot and is used to measure elements less prone to ionization such as: Aluminum, 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 give a real alternative and offer comparable results throughout the wavelength range.
• Safety Features
  - Gas Pressure Monitoring for all gasses
  - Burner Identification
  - Flame Sensor
  - Drain Trap level Sensor
  - Gas Leak Detector
  - Safety cut off switch

PG Instruments AA500F Atomic Absorption Spectrometer GRAPHITE FURNACE ATOMIZER FEATURES The integrated graphite furnace atomizer is available in 2 formats: - In the AA500G instrument the graphite furnace head is fixed into the light path. - 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 AA-Win software.

Furnace Head Design -The Transverse head is heated and cooled efficiently due to the 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 Tubes are supplied as standard and will accept volumes up to 20ul. Heating Program -Up to 10 heat stages are available. These can be set up and stored in the AA-Win software. The graphite furnace tube is cooled efficiently by an optional water circulation system.

• Safety Features
  -Argon Gas Pressure Sensor
  -Water Flow Sensor
  -Over Temperature Sensor
