atomic absorption spectrophotometer
In 1954, the Melbourne Institute of Physics in Australia exhibited the world's first atomic absorption spectrophotometer at the exhibition. The use of hollow cathode lamps has led to the development of commercial instruments for atomic absorption spectrophotometers.
Before 1959, the Soviet scholar LV. ВьBOB designed the graphite furnace atomizer. In 1960, the electrothermal atomization method (ie, non-flame atomic absorption method) was proposed, which made the sensitivity of atomic absorption analysis extremely great. improve.
