AA500 Atomic Absorption

1.75 out of 5 based on 32 customer ratings
(32 customer reviews)

The instrument is available with a flame atomiser and graphite furnace. Three flame options are available namely – Air/Acetylene, N2O/Acetylene and Air/LPG (Natural gas). The system can be fully automated via either our Universal Auto-sampler OR a Random Access Auto-sampler. Hydride analyse is also available can also be FULLY automated. The instrument is FULLY controlled via our ‘user-friendly’ software AAWin. With more than 1000 units sold World Wide the AA500 is used in many locations and for many applications and well accepted as a High Specification and reliable system.

Product Description

The AA500 Atomic Absorption Spectrometer is available in THREE configurations.

  • Flame Analysis Only (AA500F)
  • Graphite Furnace Only (AA500G)
  • Combined Flame and Furnace (AA500FG)

 

The AA500 is fully controlled by the embedded computer system and AA-Win Pro GLP Software. Three flame options are available to the user with the Air/Acetylene being the standard configuration. This flame can be used for nearly all standard elements while the N2O/Acetylene and the Air/LPG (Natural gas) are available as an option for the more demanding of elements. All three flame configurations offer coded burner for full safety protection.

Standard Features

  • Embedded PC system built into the instrument as standard on all configurations. Pre-installed UV-Win Pro software, user manuals, cook book and Windows 7 professional operating system.
  • UV-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 optimised by the AA-Win Pro software. Operating lamp current and warm-up lamp 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 optimised 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 WinPro software as well as peak height, peak area, sequential and manual integration modes.

Flame Atomiser Features

The flame atomiser 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 nebuliser 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.

N20/Acetylene

  • The N2O/Acetylene flame uses a 50mm single slot burner and is available as an optional extra. (This burner is also known as the UNIVERSAL Burner.
  • This flame configuration is used to measure elements less prone to ionization such as: Aluminium, Tin, Titanium, Calcium, Vanadium and Molybdenum.
  • Switching from Air/Acetylene to N2O/Acetylene to Flame Off is fully controlled by the AAWinPro 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 analysing 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 has a temperature range up to 3000 Degrees Centigrade.
  • The heating Program has an up to Nine Ramp Temperature program
  •  The graphite furnace head is fixed into the light path so alignment with the optical path is simple and accurate.
  •  The AA500 graphite furnace head is fixed behind the flame atomiser assembly and is motorised into position by a simple operation in the AAWinPro software. The positions for the flame and graphite are saved making it easy to swap between modes for different analysis.


Features

  •  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 atomiser. These can be set and stored within the AAWinPro 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 Software.
  •  The graphite tube is efficiently cooled by an additional water circulation system (supplied separately).

Safety Features

  •  Argon Gas pressure Sensor
  •  Water flow sensor
  •  Over Temperature Sensor
  •  Broken graphite tube protection.

    Hello,

    I would want to ask how RSD is calculated in AAwin software. The calculated value in software it seems to be too low. For an average value of 906 ppb and SD=0.73 ppb the software show RSD=82%? Could I download a new version for AAwin?
