Atomic Absorption Spectrophotometers(AAS)

AA-6300

Next Generation Double Beam
Atomic Absorption Spectrophotometer

AA-6300

The newly developed,high hroughput dynamic beam maneger system achieves measurements with the world's highest level of sensitivity (Direct determination - Flame:Pb, 0.1ppm; Furnace:Pb, 0.3ppb)

  • A next generation double beam system which drastically reduces the noise of a double beam optical system through the adoption of a high throughput dynamic beam manager system and a high speed operation digital filter.

The newly developed "WizAArd" (Windows-based 32bit)
software - a match for this electronic records era - is much more easier to understand and use, as well as being more secure

  • In order to strengthen the security of electronic records, the ability to manage using login ID names and passwords, management of usage authority restriction according to user level, electronic signatures, and audit trail functions have been equipped as standard.
  • QA/QC functionality as required by the U.S.
    Environmental Protection Agency (EPA) has been improved even further.
  • Hardware validation software is also standard equipment.

Switch smoothly between Flame and Furnace

  • All that is involved in switching from flame to furnace is to remove the burner head and put in place the furnace section. These steps require no tools, and can be done easily and speedily.
  • Furthermore, the single autosampler can be used for both flame and furnace, which negates the need to prepare the autosampler for each analysis method.

Adoption of Automatic Burner Head Height Control Mechanism

  • In addition to the automated control of the flame gas flow rate conditions, the burner head height can be automatically controlled as well. The optimal parameters for each element/ sample can be set automatically to enable continuous measurement.
