  • Page 12 Safety is an extremely important consideration for flame atomic absorption spectrophotometers using acetylene gas. The AA-7000 Series instruments are the first* ones in the world fitted with a vibration sensor as standard. They also incorporate a comprehensive range of safety mechanisms, including gas leak detectors.
  • Page 13 Safety Functions for Flame-Specification Instruments World first! –– flame extinguished automatically by vibration sensor The flame is automatically extinguished when the new built-in sensor detects vibrations. Instruments are completely safe during severe shaking caused by earthquakes. Multimode automatic gas leak check The fuel gas pipes inside the instrument gas controller are automatically checked for gas leaks when the power is turned on and when the flame is extinguished.
  • Page 14 Dual-Background Correction Functions The optimal background correction methods are installed as standard: high-speed self-reversal method (SR method) and deuterium lamp method (D method). These functions can correct for spectral interference in flame measurement. Selecting the optimal background correction method for each sample ensures accurate and reliable analysis results.
