GD320N PPM Metal Atomic Absorption Spectrophotometer
Buildin computer data processing and LCD: adopting highly integrated micro digital circuit, which is stable and reliable with the functions of integral holding, peak height and area, auto zero adjusting, deuterium lamp and background, multilinear and nonlinear curves fitting, various parameters and working curves displayed in screen and report printing, etc. GD320N Gold Tester is equipped with interface for externally linking PC.
Good basic line stability: Double-beam system of optimized design can automatically compensate the light
s ource drift and wavelength drift caused by the variation of temperature (with the function of the eliminating the affection of wavelength drift on the base line stability) and electronic circuit drift so as to reach a good basic line stability.
The cathode lamp needs not be pre-heated for long time and sample can be analyzed immediately. GD320N GoldTester is the preferable instrument chosen by users to conduct analysis of multiple kinds of elements and fast analysis of samples.
High precision of measurement: Gas path system is equipped with precision pressure stabilizing and current stabilizing devices to reach stable flame and low noise. Specially designed fine light beam passes through the flame to ensure a high precision analytical test and low characteristic concentration
Optical path of high energy: 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 intothe slit. Therefore the light flux of double beam is enhanced.
Long-life and anti-corrosive atomization system: The burner is made of new type titanium alloys, anti-corrosive and fast thermal equilibrium. It meets the requirement of measurement sensitivity without water-cooling
