AF-7550 Dual Channel Atomic Fluorescence Spectrometer

AF-7550 Atomic Fluorescence Spectrometer with Dual Channel Hydride Generation

Stock Status: On The Way


AF-7550 Dual Channel Atomic Fluorescence Spectrometer, which is a precise and intelligently controlled injection system combines a six-way valve and a variable quantitative tube. It is accurate, convenient and durable. The unique variable quantitative tube design has the advantage of an injection pump. Two elements can be measured at the same time, and it is a proper instrument for the elements of As, Sb, Pb, Bi, Te, Sn, Se, Hg, Cd, Zn, Ge. 


A highly effective gas-liquid separation system

The effective separation system allows for reduction of the colorless flame noise level, lower detection limit, expanded linear range and improved analysis accuracy.

Environmentally friendly, economical low-flow gas system

A mass flow gas control module is used to achieve precise and accurate gas flow control which can be continuously adjusted. Control is consistent, stable and reliable.

Coded hollow cathode lamp

Coded hollow cathode lamp allows the instrument to automatically recognize the element lamp, and monitor the usage of each lamp. Three-dimensional lamp position adjustment allows the lamp beam to be focused to the optimal point.

Three-dimensional adjustable infrared atomizer

The three-dimensional position adjustment allows for optimization of the atomizer focal point. By using infrared heating technology, we can heat faster, control the temperature more precisely, and improve durability.

Short focal length lens, fully enclosed non dispersive optical system.

The anti-corrosion fluid path system makes the instrument more secure and reliable.

Economical analysis, with significantly reduced argon consumption

Fast and reliable Ethernet communication

High performance auto-sampler, with automatic on-line dilution


Food, seafood, environment, geology, metallurgy, teaching and research, clinical medicine, urban water supply, sewage pollution, drinking water detection
