AAS Atomic Absorption Spectrophotometer - QT-AAS30 Series

Key Features:

  1. Total Reflection Optical System: This feature reduces energy loss, ensuring an exceptional signal-to-noise ratio and lower detection limits.
  2. Background Correction: Standard deuterium lamp background correction is available for all models. Double beam models come with high-performance self-absorption background correction as standard, with the option available for models equipped with an 8-lamp turret.
  3. Automatic Pneumatic Control Module: This feature enhances device safety and accuracy, providing better protection for both operators and the device.
  4. Automatic Vertical 4/8-Lamp Turret: The turret supports high-performance element lamps and offers 360-degree rotation, ensuring that test accuracy and reliability remain unaffected by gravity.
  5. Modular Design: The optical system and circuit feature a modular design, making maintenance and repair a straightforward process.
  6. User-Friendly Software: Operate the AAS with ease using the RGWIN AAS software under the MS Windows system, which offers professional, automatic, and user-friendly functionality, along with QA/QC capabilities.
  7. Transversely Heated Graphite Tube: This innovative feature ensures consistent gas temperature in the graphite tube, rapidly reaching atomic temperature and enhancing atomic efficiency and test accuracy. This ensures more accurate analysis results, reduces furnace body requirements, and prolongs the lifetime of the equipment.
  8. Safety Protection System: The safety protection system includes pressure monitoring to prevent the graphite furnace from working if argon pressure is too high or too low. Additionally, there's graphite tube installation self-inspection.
