The flame atomic absorption spectrophotometer offers high analysis precision and a thoughtful humanized design, fully meeting the various specific needs of different customers. A graphite furnace controller, autosampler, hydride generator, etc. can be optionally configured according to different analysis needs.
It can be widely used in geology, metallurgy, medicine, chemical industry, petroleum, agriculture, environmental protection, commodity inspection and other industries. For the analysis of trace and ultra-trace elements, in recent years it has gradually expanded from inorganic chemistry to organic chemistry.
1. Four, six or eight lamp positions selectable: automatic three-dimensional switching, energy balancing, simultaneous preheating of multiple lamp positions to save waiting time; deuterium lamp background correction and high-performance element lamps can be selected.
2. Automatic instrument setting optimization: instrument setting automatic optimization and memory function, one-key completion of scanning peak finding.
3. Data report multi-format saving and printing output: convenient for data query and comparison.
4. Software design makes operation simpler: the instrument software adopts a single-interface multi-functional window design, real-time monitoring of data changes, support for mainstream Windows operating systems, support for remote control and calibration, Chinese/English versions optional.
5. Advanced and reliable multiple safety protection system: automatically detecting and alarming on abnormal conditions such as insufficient pressure, gas leakage and flameout.
6. Expansion and coupling functions: hydride system, graphite furnace system and coupling functions.
7. Automatic online detection function.
