Atomic Absorption Spectrophotometer for analysis of major and trace elements in metallurgy, geology, mining, petroleum, etc.

The atomic absorption spectrophotometer is widely used in the analysis of major and trace elements in metallurgy, geology, mining, petroleum, light industry, agriculture, medicine, health, food and environmental monitoring.

Atomic Absorption Spectrophotometer Features:

  1. Equipped with a complete software and hardware system, it is highly intelligent, easy to use and simple to operate, and meets the requirements of authority management, audit tracking and other requirements.

  2. It has both flame and graphite furnace atomizers. The two test modes can be switched freely and matched automatically.

  3. Fully automatic eight-lamp position rotating lamp stand, automatic switching, free setting of work lamp/preheating lamp, automatic call of optimal analysis parameters and analysis conditions.

  4. Total reflection optical system, full-band achromatic, automatic wavelength scanning, automatic peak search.

  5. Both the flame and graphite furnace systems have deuterium lamps and self-priming background subtraction to meet the detection needs of complex matrix samples.

  6. Full titanium burner, stable combustion and fast heat balance.

  7. Longitudinal heating graphite furnace technology achieves uniform temperature of the graphite tube.

  8. Reliable multiple protection systems, real-time flame monitoring, acetylene leakage monitoring and protection, real-time monitoring of abnormal pressure, and cooling water monitoring.

  9. The graphite furnace atomization system has alarm functions for insufficient cooling water flow, insufficient argon pressure, excessive temperature of the graphite furnace, abnormal power supply temperature, and poor contact during graphite tube installation, and automatically cuts off the temperature rise program to ensure the safety of the operation and use process.
