电感耦合高频等离子体作为一种新的激发源(简称ICP)引入光谱分析以来,正日益以其灵敏度高,稳定性好,能同时进行多元素测定的优越性,成为溶液分析的一种强有力手段。本文报导以自由振荡型ICP光源与1米光栅摄谱仪组合的分析装置,装备有去溶与不去溶进样系统,设计了方便的炬管调节装置,改进了高频电磁场的屏蔽措施,对等离子体多种参数进行了实验选择,测定出折衷工作条件下两种进样系统的元素分析下限与精
As a new excitation source (referred to as ICP), inductively coupled high-frequency plasma has been increasingly used as a powerful analytical solution because of its high sensitivity, good stability and simultaneous multi-element determination since the introduction of spectral analysis Powerful means. In this paper, an analytical device combining free-oscillation ICP light source with a 1-meter grating spectrograph is equipped with a desolvation and non-desorption injection system, a convenient torch adjustment device is designed, shielding measures of high-frequency electromagnetic field are improved, A variety of plasma parameters were experimentally selected to determine the eclectic working conditions of the two kinds of injection system, the lower limit of elemental analysis and precision
