"电感耦合等离子体"(Inductively Coupled Plasma, ICP)是一种利用高频电磁场感应耦合产生的高温等离子体。其核心原理和工作过程如下:
感应耦合机制
高频电流(通常27MHz或40MHz)通过感应线圈产生交变电磁场。当氩气通过石英炬管时,交变磁场使气体中的自由电子加速运动,通过碰撞电离形成自持放电的等离子体焰炬。这种能量传递方式无需电极接触,故称"电感耦合"。
等离子体特性
在10,000K高温下,气体高度电离形成电中性的离子-电子混合体。其特殊环状结构分为:
炬管结构
三层同心石英管设计:
能量维持
通过涡流效应实现能量持续输入:高频电磁场诱导等离子体内部产生涡电流,电阻加热效应使气体保持电离状态。
