Atomic Absorption Spectrophotometer with Double Beam

Description

Product Description
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:
The atomic absorption spectrophotometer is quipped 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-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.
Full titanium burner, stable combustion and fast heat balance.
Reliable multiple protection systems, real-time flame monitoring, acetylene leakage monitoring and protection, real-time monitoring of abnormal pressure, and cooling water monitoring.
The laughing gas-acetylene flame effectively increases the types of test elements, with a wide analysis range and strong selectivity. Test interference is small.
Paired with the hydride generator produced by our company, it can expand the detection of arsenic, selenium, mercury, and antimony lamp elements, easily cope with the diversified problems of analysis samples, and meet the analysis needs of multiple elements.
An atomic absorption spectrophotometer is optional and can be installed freely.
