产品名称： AFS-8900 Atomic Fluorescence Spectrophotometer
●Suitable for trace analysis of twelve elements such as arsenic, mercury, selenium and antimony in samples.
●Real-time drift correction function.
●Double channel and two element automatic measurement, and the single measurement time is less than 30s.
●Integrated design of intermittent flow steam generation system and host.
●The built-in intermittent flow steam generation system, with alternating introduction of samples and carrier current, realizes on-line cleaning, eliminates cross contamination, saves the amount of samples and reagents, and eliminates waste liquid by mechanical power.
●Sample/current-carrying isolation technology to eliminate diffusion effect on measurement results.
●Single point configuration working curve; automatic dilution; automatic measurement.
●The instrument can automatically identify and monitor the service life of high-performance coded hollow cathode lamp.
●The cathode lamp adopts the modes of constant current drive and pulse power supply.
●Shielded quartz furnace low temperature atomizer can 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 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.
