    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.


    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


    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)

    Safety Features

    Argon gas pressure sensor
    Water flow sensor
    Over temperature sensor
    Broken graphite tube protection

    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:

    AA500FG-The instrument is equipped with a flame atomizer and a graphite furnace atomiser. The positioning of which is fully controlled by the embedded computer system and AA-Win Pro 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. 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.
