Introduction: As a branch of atomic spectrometry, Atomic Fluorescence Spectrometry is a newly spectral analysis technique developed in middle of 20th century. Bearing both advantages of atomic absorption spectrometry and atomic emission spectrometry and avoiding disadvantages of current analysis technique, this is a great trace elements analysis technique. As a complementarity of atomic absorption spectrometer and atomic emission spectrometer, Atomic Fluorescence Spectrometer is a measurement instrument featuring accurate, rapid, high sensitivity, simple structure, small body, and easy-to-use. AFS200 series double channel Atomic Fluorescence Spectrometer, incorporating Skyray’s many years of research experience, is a precise analysis instrument with completely independent intellectual property rights. Featuring characteristics of high performance and complete functions, this series of instruments are kindly designed for customers which can satisfy various testing requirements of them. This instrument bears extremely low detection limit to Hg, Ag elements. It is widely applied for ultratrace analysis to Hg, As, Sb, Bi, Se, Te, Cd, Ge, Pb, Sn, and Zn, featuring small body, stable performance and easy-to-use. AFS200 series Atomic Fluorescence Spectrometer incorporates 7 Skyray patents.
At present, there are two types named AFS200N(Normal) and AFS200T(Technical), enjoying same main configurations except gas flow control system. AFS200N:integrated gas flow control system AFS200T: double channel mass flow controller—gas flow control system Performance Advantages 1,Free observation of flame Update former flame observation window with built-in flame observation device for free observation of flame, which greatly reduces outside interference and it is convenient for use. 2,Optical source hot—plugging device This instrument achieves free change of lamps without turning off main power of instrument which reduces preheat time of lamps. 3,USB2.0 port Give up old 232 port and employ new USB2.0 port, which improves transmission speed, compatible to new computer system. 4,Gas flow control system Automatic gas flow control system is applied in this instrument which is rapid and stable in gas flow control. It also can detect malfunction of instrument. Ar flow will be cut off automatically to save gas reservation when instrument is not working. AFS200N employs integrated gas flow control system, monitoring gas pressure through pressure switch; AFS200T is equipped with double channel mass flow controller—gas flow control system with precision of 1ml/min. 5,Environmental friendly Special exhaust gas collecting device is equipped to be environmentally friendly and provide safer operation for analytical personnel. 6,Intelligent high-performance hollow cathode lamp Our corporation’s patented intelligent high-performance hollow cathode lamp is used; element type and manufacturing no. can be automatically identified, working life of optical source can be recorded to ensure best working conditions, etc. 7,Optical system New non-dispersive optical system is applied, which greatly increases testing sensitivity and making instrument structure more compact and easy-to-use. 8,Double channel design Simultaneous analysis of two elements and improved function of single path, testing sensitivity and element detection limit are significantly improved. 9,Frontally—positioned optical source Frontally—positioned design is used instead of back—positioned design of high-performance hollow cathode lamp which does great helps to customers 10,Exterior design Streamlined sheet metal design and slide door mechanism, which is simple and elegant. 11,Use standard solution to prepare standard curve Prepare highest concentration standard solution to create standard curve, saving preparation time of standard samples, auto-dilution of high concentration samples and auto-cleaning of tubes. 12,Low—temperature atomization ignition Longer working life of furnace wire and more stable flame 13,Protected quartz tube atomizer Effectively reduces put out of fluorescence and significantly improves testing sensitivity and signal-to-noise ratio 14,High-efficient level 2 gas/liquid separation Efficient separation of gas and liquid, removing water vapor effects on test results to the m. 15,Software Atomic fluorescence software workstation of proprietary intellectual property is developed with user-friendly operating interface: Chinese/English software interface, automatic qualitative and quantitative analysis, automatic calculation of sample content, auto-generation of test reports, etc. Technical Specifications 1,Analytical elements: As,Sb,Bi,Hg,Se,Te,Pb,Sn,Ge,Zn,Cd, etc. 2,Detection limit of typical elements: As,Sb,Bi≤0.01ng/ml,Hg≤0.001ng/ml 3,RSD: ≤ 1% (typical elements) 4,Linear range: above 3 orders of magnitude 5,Channel interference: ≤ 2% 6,Stability: ≤ 2% 7,Ambient temperature: 5℃-35℃ 8,Ambient humidity: ≤80% 9,Power input: 220V±22V,50Hz±1Hz 10,Dimension: 610mm×514mm×545mm(L×W×H) 11,Weight: 60Kg Standard Configuration 1, Instrument: 1 set 2, Accessories: spare channel, toolkit, spare parts Optional Configuration 1, Automatic sampler AS100 2, Brand computer 3, Brand printer
