Function of AFS-100 Atomic Fluorescence Spectrometer

Single channel and dual channel simultaneous detection function.
◆ Light source system: The hollow cathode lamp adopts a new pulse modulation/constant current drive power supply method.
The hollow cathode lamp adopts coding technology, and the instrument automatically identifies the hollow cathode lamp and can monitor the working status and service life of the hollow cathode lamp.
Detection system: Imported photomultiplier tubes are used.
Injection system: using intermittent flow injection device. (Alternate introduction of sample blanks to avoid cross contamination of samples and ensure measurement accuracy)
Adopting a new intermittent flow reaction system without residual vapor, the reaction efficiency is higher
◆ Adopting an efficient surge type two-stage chemical gas-liquid reaction separation device, the chemical reaction is more efficient and the gas-liquid separation effect is better, especially suitable for the determination of complex samples such as rocks, minerals, and soils
◆ Equipped with a carrier gas steady flow device, it can not only eliminate bubbles generated by borohydride online, but also reduce the diffusion effect between reagents and improve the stability of the instrument
Stable flow separation type gas path generation device.
◆ Friendly software interface, recommended instrument testing conditions, graphical display and playback of test data, statistics and queries, various functions such as saving, outputting, backing up and printing of graphics and data pages.
Instrument self check and gas cut-off warning protection function.
