Model AF-7550 double-channel hydride-atomic fluorescence photometer adopts a combination of six-way injection valve and variable quantitative tube, which makes injection accurate, convenient and durable. Unique variable quantitative tube design has the advantages of injection pump;
Gas-liquid separation system with more thorough separation:
The gas-liquid separation is more thorough, the noise level of colorless flame in the true sense is greatly reduced, the detection limit is greatly improved, the linear range is broadened, and the analysis accuracy is improved;
Humanized and Environmental Protection Solar Term Gas Path Design;
AF-7550 double-channel hydride-atomic fluorescence photometer adopts the gas path control module of mass flowmeter, which controls the gas flow accurately and accurately, and the flow rate can be continuously adjusted, with good consistency, stability and reliability;
Coded hollow cathode lamp:
Model AF-7550 double channel hydride-atomic fluorescence photometer adopts coded hollow cathode lamp, which can automatically identify element lamp and monitor the service life of hollow cathode lamp. Three-dimensional adjustable lamp holder design can make the element light beam focus the flame position better;
Three-dimensional adjustable far infrared heating atomizer;
The accurate position of the flame irradiated by the light can be adjusted, and the advanced far infrared heating atomizer is used, so that the instrument heats up faster, the constant temperature accuracy is higher, and the service life is longer;
Short focal length lens concentrating, fully enclosed non-dispersion optical system;
Strong anti-corrosion liquid circuit system, the instrument is safer and more reliable in use;
The analysis cost is low and the argon consumption is greatly reduced;
Adopt network port communication, fast speed and strong stability;
Automatic sampler with outstanding performance.
