Major Technical Features
Being able to²
- Measure Many Elements and to Measure Two Elements at Same Time Suitable for use of Trace and Ultra Trace Analysis of Eleven Elements, such as As, Sb, Bi, Se, Sn, Pb, Ge, Te, Zn, Cd, Hg.
- Raise Two Times of Working Efficiency of Instrument Due to Seamless Combination of 8-wayn Sample Injection Valve and Peristaltic Pump (Invented, Pending Patent), it Realizes Continuous Flowing, Discontinuous Sample Injection, Alternatively Injecting Samples in Two Channels, and Alternatively Analysis. When One Channel is Washing and Injecting Samples, another Channel can Perform Analysis. And there is no Cross Contamination. First Invented Infrared Ray²
- Controlled, Membrane Separation Type Gas-Liquid Separation System Usage of Infrared Ray Controlled, Membrane Separation Type Gas-Liquid Separation System (Pending Patent) makes that Waste Liquid is not Discharged by Pump. Separation of Gas and Liquid is more Completely, Really Realizing Flame of No Color. Noise level is Reduced Substantially and Limit of Detection is Improved Greatly and Broaden Linear Range. Automatically Light Ar, H2 Flame at Low²
- Temperature Improve Sensitivity by Several Folds. “Memory” Effect is Smaller.General Power Supply for High Intensity Hollow Cathode Lamp and²
- Specialized Hollow Cathode Lamp Offer Users Convenient Light Source that can be Changed at any Time based on User’s Needs.Far Infrared Heated²
- Atomizer Use Advanced Far Infrared Heated Atomizer, making Temperature Rise Quickly, Accuracy of Constant Temperature High, and Working Life Long. Automatically Controlled Air Routes²
- This Instrument Synthesizes Large Volume Advanced Circuit Control System, making Air Routes be able to Automatically Controlled, to Automatically Protected, to Ensure Safety of Analysis. Safe²
- Reliable Since Liquid Route System Adopts Strong Corrosive-Resistant Material, Instrument is more Safe and Reliable in Usage Cheap Analysis Cost²
- Consumption of Reagent, Sample and Arn is Reduced Substantially.
- Automatic Computer System Analysisn AF-7500 Windows Application Programs make Analysis Procedures Automatic. User can Use this Program to Realize Sampling, Spectrogram Display and After Treatment, Generation of Sample Table, Result Calculation, Result Printing and other Functions. Computer System Uses Duel Channel Analysis and can Control Each State of Instrument According to Parameters Designated by User, Realizing Technical Actions including Automatically Lighting, Automatically Preheat, Temperature Rising by Segment and etc.
- Compact Instrument Volume Since Large Volume of Latest Photoelectric Technologies are Used, Volume of Whole Instrument is Reduced to 1/2 of Products of Same Category in China, especially Suitable for Use in Places having High Requirement for Instrument Space, for example, on Ships.
- Automatic Sample Injector Large Volume Sample Rack Containing 130 Cups. Simple Structure and Accurate and Reliable Actions. Small Volume, Light Weight. Simple Connection to Major Unit. Quick Switch between Manual and Automatic States
