AA-7050 atomic absorption spectrophotometer Features
1.Configure the graphite furnace visual system, which can better help users locate the injection needle, observe the state of the sample in the graphite tube, and optimize the graphite furnace temperature program, etc.
2.Configure the graphite furnace air-saving mode, which improves the effective utilization of gas protection, can increase the gas use time by a factor of two, and reduce the use cost of the instrument
3.Configure graphite furnace double internal gas circuit, so that users can add an additional auxiliary gas outside the protective gas to help the sample ash and get better results
4.The software has a variety of temperature correction procedures, can use domestic and imported graphite tubes
5.With code lamp function
6.With multi-element analysis function, equipped with AS-600 autosampler to realize automatic determination of multiple elements Technical parameters
