Atomic Fluorescence Spectrometer

I. Product Introduction

The atomic fluorescence spectrometer adopts a highly reliable, highly intelligent, highly automated and maintenance-free human-machine interaction design, solving the pain points of traditional atomic fluorescence. The instrument has a wide range of uses, and its application fields include the detection of trace and ultra-trace elements in food hygiene, urban water supply and drainage, environmental protection, agriculture, metallurgy, cosmetics, pharmaceuticals, geology and commodity inspection. Examples include environmental sample testing, harmful element testing in cosmetics, food hygiene inspection, geological and metallurgical sample inspection, urban water supply and drainage detection, marine environment and aquatic product detection, natural drinking mineral water detection, education and scientific research, clinical medical sample inspection, traditional Chinese patent medicine inspection, and agricultural environmental protection and agricultural product detection.

II. Features

Measuring mode: dual-channel and two-lamp positions; single-element testing or simultaneous dual-element testing selectable; simultaneous dual-element determination improves instrument analysis speed.

Detection items: trace analysis of a dozen or more elements in samples, such as As, Sb, Bi, Hg, Se, Te, Sn, Ge, Pb, Zn, Cd and Au.

Detection light source: adopts a beam-type pulse power supply mode (square wave to reduce interference); specially made high-intensity hollow-cathode lamps; the instrument can automatically identify energy and automatically proportion and adjust it.

Optical system: short-focal-length lens focusing, non-dispersive fully enclosed light-shielded dimming system.

Sample introduction system: fully automatic built-in intermittent pump sample introduction system, capable of automatic dilution and precise online adjustment of the reducing agent injection volume.

Atomizer: low-temperature automatically ignited argon-hydrogen flame, shielded quartz atomizer.

Protection device: self-check on startup, automatic gas path control, automatic protection and automatic alarm system.

Vapor removal device: equipped with a chemical vapor generation gas-liquid separation device and an automatic water vapor removal device.

Trap device: equipped with a hydride generation atomic fluorescence trap device for harmful elements in the exhaust gas, effectively preventing secondary pollution to the environment.

Dedicated operating software: Chinese window operating software suitable for XP/Win7/Win8/Win10.

Reserved upgrade interface: can be coupled with liquid chromatography and other devices for elemental speciation and valence state analysis of As, Se, Sb, Hg and other elements.

Automatic standard curve: automatic single-point standard curve preparation, with a curve linearity coefficient >0.999, and online change of injection volume.

Precise flow control: modular mass flow meter design; flow is controlled by computer, with accurate flow and safe gas path.
