Specialist Atomic Absorption Spectrophotometer for petroleum, light industry, agriculture, medicine, health, food and environmental monitoring, 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:
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.
Working methods can be stored, eliminating the need to repeatedly set test conditions, streamlining the detection process, avoiding duplication of work, and greatly saving users' time and cost.
Fully automatic eight/four lamp position rotating lamp stand, automatic switching, free setting of work lamp/preheating lamp, automatic call of optimal analysis parameters and analysis conditions.
Total reflection optical system, full-band achromatic, automatic wavelength scanning, automatic peak search.
It has both deuterium lamp and self-priming background subtraction to meet the detection needs of complex matrix samples.
Longitudinal heating graphite furnace technology achieves uniform temperature of the graphite tube.
The graphite furnace atomization system has alarm functions for insufficient cooling water flow, insufficient argon gas pressure, excessive temperature of the graphite furnace, abnormal power supply temperature, poor contact in the installation of graphite tubes, and automatically cuts off the temperature rise program to ensure the safety of the operation and use process.
It can be used with an automatic sampler for safe and efficient analysis. The hanging installation is simple and easy to debug, maximizing the user's work efficiency.
