Universal Autosampler for Atomic Absorption Spectrometer AA500

The AS 500 Auto sampler is an accessory specifically designed for the AA500 Atomic Absorption Spectrophotometer. It can automate the operation for standard samples and unknown samples. It can be used for both flame and graphite furnace instruments.

 

Specifications:

Graphite furnace mode:

• There are 76 sample vials in the sample tray (10 for standard samples, 60 for unknown samples and 6 for modifier solutions).
• Sample vial: 1.5mL; modifier vial: 12mL.
• Reproducibility: Cu<2%, Cd<2%.
• Dilution function: the maximum dilution multiple is 120, linearity less than 0.995.
• Addition function.
• Oscillation function: Shakes up the dilution sample.

Flame mode:

• There are 38 sample vials in the sample tray (6 for standard samples, 32 for unknown samples).
• Sample vial: 6mL; Standard sample vial: 12mL.
• Reproducibility: Cu<0.6% (Air-Acetylene method), Cu<1% (Air-LPG method), Ba<1% (Nitrous oxide-Acetylene method)
• Pressure protection function: If the pressure of Argon is less than 30psi, the wash function will fail and a fault will be displayed by software.
• Horizontal adjustment: Adjust the position of the injection head in the graphite tube.
• Add modifier automatically.
