Jitian AFS-9330 fully automatic six lamp dual sequence injection atomic fluorescence spectrophotometer

detailed description:Atomic fluorescence spectroscopy analysis is a new spectroscopic analysis technique proposed and developed in the mid-1960s. It has the advantages of both atomic absorption and atomic emission spectroscopy techniques and overcomes some of their shortcomings. It has the characteristics of high analytical sensitivity, low interference, wide linear range, and the ability to analyze multiple elements simultaneously. It is an excellent trace analysis technique.

•Gas system:Electromagnetic valve controlled flow meter, mass flow meter

•Sample injector:3D automatic sampler, polar coordinate automatic sampler

•Hydrogen Generation System (Steam Generation System):Peristaltic pump, sequential injection pump

•Atomizer:Low temperature argon hydrogen flame atomizer (double-layer shielded quartz core)

•Excitation light source:Specially designed high-intensity hollow core cathode lamp (As, Sb, Bi, Hg, etc.). The application of short pulse high current power supply technology has greatly improved its service life and stability.

•Detector:The sun blind photomultiplier tube has a detection wavelength range of 160nm to 320nm, greatly reducing the interference of visible light.

•Fully automatic dual sequence injection system:High injection accuracy, stable propulsion, accurate injection volume, and stable injection volume after long-term use. Reliability greatly improves its automation level and enables the "intelligent" operation of instruments.
