AA-7001 Flame Graphite Furnace Atomic Absorption Spectrophotometer Introduction
• Suspension design of the optical system, vibration, ambient temperature change does not affect the stability of the instrument.
• The world's first to integrate flame atomizer / graphite furnace atomizer, graphite furnace power supply and optical and electronic detection system in the same instrument body, it is one of the most compact AAS in the world.
• The first domestic all-titanium atomization combustion system. Using aerospace high-tech, pure titanium atomizing chamber and combustion head in the lost wax precision casting industry, it has excellent corrosion resistance, oxidation resistance, high temperature resistance and long service life.
• It is the first domestic company to adopt 1,800 diffraction gratings with sufficient energy and high resolution.
• The single-beam optical system also has sufficient energy to achieve low detection limits for elements such as arsenic and selenium.
• Fully automatic flame / graphite furnace switching in two seconds.
• Carefully designed tritium lamp buckle background technology and self-absorption full-band buckle background technology, the correction results are more accurate. Optimized power supply technology extends the life of the lamp.
• Safe and reliable control alarm device to ensure over-current protection of hollow cathode lamp, gas / shield gas under-pressure protection, gas leakage alarm, graphite furnace overheat protection and flame abnormal state protection.
• It can be equipped with the domestic first HG-01 type ceramic heating tube hydride generating device, with high sensitivity and accurate analysis of As, Pb, Se, Hg and other elements.
• It can be equipped with a graphite furnace automatic sampler, which can automatically prepare standard solutions and realize automatic analysis. Features
