AF-7500/7500B Dual-channel Hydride-Atomic Fluorescence Spectrophotometer

AF-7500 fully automatic atomic fluorescence spectrophotometer is a new generation atomic fluorescence spectrophotometer successfully developed by our company relying on its own technical advantages. The instrument integrates the latest achievements of current modern science and technology, computer and photoelectric technology, providing users with a simple, efficient, safe and reliable analysis method.

Adopts dual-channel technology, can analyze two elements simultaneously, suitable for trace and ultra-trace analysis of twelve elements such as As, Sb, Bi, Se, Sn, Pb, Ge, Te, Zn, Cd, Hg, Au.

Adopts peristaltic pump and eight-way valve sampling. While the first sample is analyzed, the second sample is sampled in the quantitative tube. The quantitative tube sampling volume is accurate, saving operation time. Compared with other instruments of the same type, the total analysis time is almost shortened by half, accelerating the analysis speed.

Zero-time automatic cleaning, dual quantitative tube alternate sampling. While one tube is sampling, the other tube is cleaning, no additional time for cleaning, double improvement in cleaning efficiency and sampling efficiency.  

The gas-liquid separation system uses secondary separation (one-time space-time separation, one-time membrane separation), minimizing water vapor influence and improving analysis accuracy. This gas-liquid membrane separation technology has obtained national patent (patent number: 200720104068.X), and at the same time uses infrared sensor to control liquid level, eliminating the impact of liquid level on analysis.  

Shielded low-temperature ignition quartz atomizer, adopts far-infrared heating method, fast instrument heating, long service life.
