ICP用石英玻璃制的放电管发生等离子体,把频率27百万赫兹,输出功率1～2千瓦的高频电通过感应线圈导入氩气中,进行忒斯拉感应圈(Tesla Coil)放电。ICP放电管的特点是没有电极,等离了体呈火焰状,所以非常稳定。等离子体的温度可达五千到一万度。ICP分析时,要把试料溶液吹成雾状,然后导入等离子体中心,试料在高温火焰中一面被加热,一面向上升。通常,在距离感应线圈上方十五毫米处,大部分元素的谱线发出最强的光,从这个部位把光导入分
ICP Plasma was generated from a discharge tube made of quartz glass, and high-frequency electricity having a frequency of 27 million hertz and an output of 1 to 2 kilowatts was introduced into the argon gas through an induction coil to discharge a Tesla Coil. ICP discharge tube is characterized by no electrode, the plasma was flaked, so very stable. The temperature of the plasma can reach 5,000 to 10,000 degrees. ICP analysis, the sample solution should be blown into a mist, and then into the plasma center, the sample was heated in a high-temperature flame, one side up. Normally, most of the elemental lines emit the strongest light at a distance of 15 mm above the induction coil, directing light from this point
