The AF-7500 fully automatic atomic fluorescence spectrometer is a new generation of atomic fluorescence spectrometer independently developed by our company relying on its own technical advantages. The instrument integrates the latest achievements of modern science and technology, computer and optoelectronic technology, providing users with a simple, efficient, safe and reliable analytical method.
AF-7500/7500B Double Channel Hydride-Atomic Fluorescence Photometer
The dual-channel technique can be used to analyze two elements simultaneously, suitable for trace and ultra-trace analysis of As, Sb, Bi, Se, Sn, Pb, Ge, Te, Zn, Cd, Hg, Au and other twelve elements.
Using peristaltic pump and eight-way valve sampling, the first sample analysis, at the same time, the second sample for quantitative tube sampling. Quantitative tube sampling volume, accurate, saving the operation time, compared with other instruments of the same type, the total analysis time is almost shortened twice, accelerated analysis speed, the sampling system obtained national patent. (Patent No.: ZL 20062001 2910.2)
Zero-time automatic cleaning, double-dosing tubes are alternately injected, one tube is injected, and the other tube is being cleaned at the same time, no need to spend additional time cleaning, and the cleaning efficiency and injection efficiency are both improved.
The gas-liquid separation system uses secondary separation (primary space-time separation, primary membrane separation), which minimizes the influence of water vapor and improves the analysis accuracy. This gas-liquid membrane separation technology has obtained a national patent (patent, no. 200720104068. X), and an infrared sensor is used to control the liquid level, which eliminates the influence of the liquid level on the analysis. This infrared sensing liquid level control device has obtained a national patent.
The shielded low-temperature ignition quartz atomizer adopts far-infrared heating method, and the instrument heats up quickly and has a long service life.
