原子吸收分光光度计的基本原理是仪器从光源辐射出具有待测元素特征谱线的光,通过试样蒸气时被蒸气中待测元素基态原子所吸收,由辐射特征谱线光被减弱的程度来测定试样中待测元素的含量。原子吸收分光光度计一般由光源(单色锐线辐射源)、原子化系统(分为火焰原子化、石墨炉原子化和氢化物发生原子化系统)、分光系统(单色 The basic principle of atomic absorption spectrophotometer is that the instrument radiates the light with the characteristic line of the element to be measured from the light source and is absorbed by the ground state atoms of the element to be measured in the vapor when it passes the sample vapor and is attenuated by the radiation characteristic spectrum light To determine the content of the test element in the sample. Atomic absorption spectrophotometer generally consists of light source (monochromatic sharp line radiation source), atomization system (divided into flame atomization, graphite furnace atomization and hydride generation atomic system), spectroscopy system (monochromatic
