Leírás és Paraméterek

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 autosampler 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 autosampler 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 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.
