AF-7550 double channel hydride-atomic fluorescence photometer Introduction
The AF-7550 dual-channel hydride-atomic fluorescence photometer uses a six-way sampling valve and a variable quantitative tube, which is accurate, convenient and durable. The unique variable quantitative tube design has the advantages of a syringe pump. The AF-7550 dual-channel hydride-atomic fluorescence photometer uses a mass flow meter gas path control module. The gas flow control is precise and accurate. The flow rate can be continuously adjusted, with good consistency, stability, and reliability. Features
1.Precise and intelligent sampling method design;
The combination of the six-way sampling valve and variable quantitative tube makes the injection accurate, convenient and durable. The variable quantitative tube design has the advantages of a syringe pump;
2.Gas-liquid separation system with more complete separation
The gas-liquid separation is more thorough, the colorless flame noise level is greatly reduced, the detection limit is improved, and the linear range is widened, and the analysis accuracy is improved;
3.Humanized, environmentally friendly and gas-saving air circuit design;
Adopt mass flow meter gas path control module, the gas flow control is precise and accurate, the flow rate can be continuously adjusted, the consistency is good, stable and reliable;
4.Coded hollow-core cathode lamp;
Using coded hollow-core cathode lamps, the instrument automatically recognizes element lamps and can monitor the service life of hollow-core cathode lamps. The three-dimensional adjustable lamp holder design can make the element lamp beam better focus on the appropriate position of the flame;
5.Three-dimensional stereo adjustable far infrared heating atomizer;
The position of the light irradiating the flame can be adjusted, the advanced far infrared heating atomizer is used, the instrument heats up faster, the constant temperature accuracy is higher, and the service life is longer;
6.Short focal length lens condensing, fully enclosed non-dispersion optical system;
7.Strong anti-corrosion fluid system, the instrument is safe and reliable in use;
8.Low analysis cost and reduced argon consumption;
9.Using network port communication, fast speed and strong stability;
10.Autosampler with excellent performance.
