Fluorescence Spectrometer (Model:AFS200)

Atomic Fluorescence Spectrometry is a spectral analysis technique developed bearing both advantages of atomic absorption spectrometry and atomic emission spectrometry for trace elements analysis. Atomic Fluorescence Spectrometer is a measurement instrument which is known for accurate, rapid, highly sensitive result and is easy-to-use.

AFS200 series double channel Atomic Fluorescence Spectrometer 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.

Application Fields:-

Atomic Fluorescence Spectrometer is applied in wide fields, covering environmental detection, anti-epidemic, food hygiene inspection, pharmaceutical inspection, city water supply and drainage inspection, cosmetic inspection, soil fertilizer detection, clinical medicine sample testing, agricultural products inspection, geological detection, metallurgy sample detection, teaching research, etc.

Features:-

•Free observation of flame greatly reduces outside interference and it is convenient for use.
•The instrument achieves free change of lamps without turning off main power of instrument which reduces preheat time of lamps.
•Automatic gas flow control system is applied for rapid and stable in gas flow control. It also can detect malfunction of instrument.
•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.
•Special exhaust gas collecting device is equipped to be environmentally friendly and provide safer operation for analytical personnel.
•Intelligent high-performance hollow cathode lamp
•Non-dispersive optical system is applied, which greatly increases testing sensitivity and making instrument structure more compact and easy-to-use.
•Simultaneous analysis of two elements and improved function of single path, testing sensitivity and element detection limit are significantly improved.
•Low—temperature atomization ignition
•High-efficient level 2 gas/liquid separation
•Atomic fluorescence software workstation is developed with user-friendly operating interface
