Introduction to Shimadzu Atomic Absorption Spectrophotometer AA-6650F

The Shimadzu Atomic Absorption Spectrophotometer AA-6650F is a high-performance analytical instrument developed by Shimadzu Corporation, designed for the precise determination of metal elements in samples. As part of the AA-6800/6650 series, the AA-6650F integrates flame and graphite furnace atomization technologies, supporting automatic switching between dual modes, making it suitable for high-sensitivity analysis in environmental monitoring, food safety, pharmaceuticals, and scientific research.

Key Features

1. Dual Atomizer Design: Automatically switches between flame and graphite furnace modes—flame mode for routine elemental analysis and graphite furnace mode for trace-level elements (e.g., lead, cadmium) with higher sensitivity.
2. Optical System: Equipped with a double-beam optical path to minimize light source fluctuations, along with a high-resolution monochromator and photomultiplier detector, ensuring low noise and high stability.
3. Safety & Automation: Features built-in gas leakage detection to prevent combustion hazards; software supports preset conditions and data storage, simplifying operation.

Technical Specifications

• Wavelength Range: 190–900 nm, covering characteristic absorption lines of most metal elements.
• Detection Limits: Flame mode achieves ppm-level detection, while graphite furnace mode reaches ppb-level (element-dependent).
• Gas Requirements: Compatible with acetylene-air and nitrous oxide-acetylene flames, requiring specialized pressure regulators.

Applications

The AA-6650F is widely used in water quality testing (e.g., heavy metal pollution), pharmaceutical impurity analysis, and industrial material quality control. Compliant with GLP standards, its traceable data makes it ideal for regulated laboratories.

Maintenance & Precautions

Regularly inspect gas line seals to prevent leaks; avoid acetone solvent leakage from acetylene cylinders. Hollow cathode lamps require warm-up and should be protected from vibration to extend lifespan.

With its reliability, flexibility, and high precision, the Shimadzu AA-6650F remains an essential tool for atomic absorption spectroscopy analysis.
