AA-7003 Series Automatic 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
1. The PC performs automatic control and data processing on the instrument
2. Automatic positioning of wavelength, automatic switching of slit, automatic setting of lamp current and gain. These tasks can be completed in 40 seconds, this indicator reaches the current international advanced level
3. The six-lamp revolving turret is completely controlled by the computer, and the element lamps are automatically selected. Realize the automatic and orderly analysis of the content of up to six elements in the sample.
4. Automatic ignition, automatic control of gas flow, automatic alarm for leakage.
5. Optional perfect nitrous oxide / acetylene gas system, analyze more than 30 kinds of high temperature elements
AA-7003 series automatic flame graphite furnace atomic absorption spectrophotometer integrates flame atomizer / graphite furnace atomizer, graphite furnace power supply and optical and electronic detection system in the same instrument body, which is the most compact AAS in the world one. The AA-7003 series automatic flame graphite furnace atomic absorption spectrophotometer single-beam optical system has sufficient energy to obtain low detection limits for elements such as arsenic and selenium.
