产品名称： AFS-9710/9750/9770 Atomic Fluorescence Spectrophotometer
●Suitable for trace analysis of twelve elements such as arsenic, mercury, selenium and antimony in samples.
●AFS-9710/9750 can measure two elements simultaneously while AFS-9770 can measure four, and the measurement time of a single sample is short.
●With ultra quiet and high-speed operation, the polar coordinate sampler can support three kinds of sample trays (69 positions with 25mL, 134 positions with 15mL and 183 positions with 10mL).
●AFS-9750 adopts ten rollers and six channel large peristaltic pump to ensure stable sample injection and effectively reduce pulsation effect.
●The application technology of pinch valve replaces the traditional check valve and multichannel valve to avoid reagent contact with the valve body. It has no corrosion, no memory, high reliability and a service life of more than 500,000 times.
●Special technology for the combination of syringe pump and peristaltic pump, which has the advantages of the fast speed of peristaltic pump, the accurate injection of syringe pump and online cleaning.
●Single point configuration of working curve; automatic dilution; automatic measurement.
●Sample/current-carrying isolation technology to eliminate diffusion effect on measurement results.
●Shielded quartz furnace low temperature atomizer to reduce fluorescence quenching and gas phase interference and improve atomization efficiency.
●New airtight two-stage gas-liquid separation device without liquid addition and waste discharge.
●The instrument can automatically identify elements and monitor the service life of high-performance coded hollow cathode lamp.
●The gas circuit system adopts array structure and is equipped with new throttle device to effectively save argon consumption.
●The instrument has the functions of boot self-check, automatic diagnosis and automatic fault alarm.
●The argon-hydrogen flame observation window is designed to monitor the flame state in real time.
●The circuit system adopts the card structure design of highly integrated functional board with strong and weak current separation.
●The software is compatible with windows7/8/10/XP system and has a powerful expert online help system.
●Software data can be quickly imported into Excel to realize network resource sharing.
●Speciation analysis interfaces are reserved to meet more functional requirements of users.
It is applicable to the fields of environmental protection, food safety, disease control, medicine and medical treatment, health and epidemic prevention, agriculture, geology and mining, metallurgy, cosmetics, soil, urban water supply and drainage, teaching and research, etc.
