Product introduction
AAS320 Atomic Absorption Spectrophotometer is applied to micro and trace metallic elements test, covering over 30 elements. The instrument has simple structure, provides fast test, with good repeatability and less interference, especially suitable for testing Cu, Zn, K, Na, Au, Ag, etc.
Feature
Stable and reliable structure
•Gas path system is equipped with precision pressure stabilizing and current stabilizing devices to reach stable flame and low noise.
•A total reflection system is adopted to eliminate color difference in full range.
•By means of chemical conversion, a round light spot of the light source becomes a long light spot, which enters into the slit.
•Special devices of quick gas conversion and safety protection can be used to analyze air-acetylene flame.
High precision measurement
•Automatically compensate the light source drift and wavelength drift caused by the variation of temperature and electronic circuit drift.
•Gas path system is equipped with precision pressure stabilizing and current stabilizing devices to reach stable flame and low noise.
Multi-functional analysis mode
•For methods of flame absorption, flame emission, graphite furnace atomic absorption and hydride generation.
•The analytic elements to reach more than 60.
