AFS-8900 atomic fluorescence photometer Features: 1. Suitable for trace analysis of twelve elements such as arsenic, mercury, selenium, lead, antimony, tin, antimony, bismuth, cadmium, antimony, zinc and gold. 2. Simultaneous measurement of two elements and two elements can realize single element measurement and simultaneous determination of two elements. In chemical analysis, the channel integration technology with technology can increase the luminous intensity of the light source, thereby further reducing the detection limit of the instrument, especially Trace analysis significantly improves the stability and repeatability of the instrument to meet the higher analytical and measurement needs of customers. 3. Injection system: designed with technology single-pump pump - intermittent flow without residual vapor generation hydride reaction system, multi-function reaction module device, sample and blank alternately introduced, online cleaning, mechanical power to eliminate waste liquid, eliminate Cross-contamination, saving sample and reagent dosage. Pump speed, sampling time, etc. can be adjusted by themselves, and the single measurement time is less than 30 seconds. 4. The newly designed high-efficiency inrush-flow gas-liquid separation device with technology has more complete chemical reaction and better gas-liquid separation effect. 5. The new closed-stage two-stage gas-liquid separation device is adopted, without adding liquid and discharging. 6. Autosampler: External disc type, single sample tray up to 183 polar autosampler, and supports semi-automatic measurement. Ultra-quiet and high-speed operation, the newly designed technology of automatic syringe cleaning device, full-line one-button cleaning and other functions, effectively reduce cross-contamination during measurement of different samples. 7. Light source system: The special coded hollow core cathode lamp is used, the instrument automatically recognizes the elements, and can monitor the service life of the air core cathode lamp. The air core cathode lamp adopts constant current driving and pulse power supply mode to improve its emission intensity and efficiency and prolong its service life. 8. Optical system: short focal length penetration concentrating, non-dispersive full-closed light-proof dimming system, and device for removing stray light. 9. The instrument can automatically dilute high concentration samples. 10. Specially designed shielded quartz furnace low temperature atomizer to reduce fluorescence quenching and gas phase interference and improve atomization efficiency. 11. Advanced membrane separation gas-liquid isolation device. 12. Pneumatic system: It adopts array structure, automatic and precise control of gas flow, and has a new type of gas-saving device, which effectively saves argon consumption. Turn off the power automatically. 13. The instrument has the functions of power-on self-test, automatic diagnosis and automatic fault alarm. 14. With an external argon hydrogen flame observation window, the flame state can be monitored in real time. 15. The circuit system adopts strong and weak power separation, high integration function board circuit structure. 16. Dedicated Win2000, XP, 7, 8 system operation software, with a powerful expert online help system. 17. The software can realize the rapid import of measurement data into EXCEL to realize network resource sharing. 18. It has a device capable of removing harmful gases such as mercury vapor in the exhaust gas, and reduces physical damage to the experimenter. 19. Reserved form interface, upgradeable morphological analyzer for valence analysis of arsenic, mercury and selenium. Technical Parameters: Temperature: 0 ° C ~ 45 ° C Humidity: ≤90% Power: 200W Machine size: 108cm; 45cm; 43cm (length; width; height) Weight: about 70kg
The AFS-8900 atomic fluorescence spectrophotometer uses a built-in intermittent flow vapor generation system (patent). Samples and carrier currents are introduced alternately to achieve online cleaning, eliminate cross-contamination, save sample and reagent usage, and remove waste liquid by mechanical power. AFS-8900 atomic fluorescence spectrophotometer is suitable for the trace analysis of twelve elements such as arsenic, mercury, selenium, antimony in the sample.
