AFS-100 atomic fluorescence spectrophotometer

AFS-100 atomic fluorescence spectrophotometer

Features:

1. Single-channel, dual-channel simultaneous detection function.

2. Light source system: The air core cathode lamp adopts a new pulse modulation/constant current drive power supply mode.

3. The air core cathode lamp adopts coding technology, the instrument automatically recognizes the air core cathode lamp, and can monitor the working state and service life of the air core cathode lamp.

4. Detection system: Adopt imported photomultiplier tube.

5. Injection system: use intermittent flow sampling device. (The sample blanks are alternately introduced to avoid cross-contamination of the sample and ensure measurement accuracy)

6. Using a new type of intermittent flow without residual vapor generation reaction system, the reaction efficiency is higher

7. It adopts high-efficiency inrush two-stage chemical gas-liquid reaction separation device, which has more complete chemical reaction and better gas-liquid separation effect. It is especially suitable for the determination of complex samples such as rock and minerals.

8. With carrier gas steady flow device, it can eliminate the bubbles generated by potassium borohydride online, reduce the diffusion effect between reagents, and improve the stability of the instrument.

9. Steady flow separation type gas path generating device.

10. Friendly software interface, recommend the best instrument test conditions, graphical display and playback of test data, statistics and query, various graphics, data page save, output, backup and print functions.

11. Instrument self-test and gas-break warning protection function.
