"電感耦合等離子體"(Inductively Coupled Plasma, ICP)是一種利用高頻電磁場感應耦合産生的高溫等離子體。其核心原理和工作過程如下:
感應耦合機制
高頻電流(通常27MHz或40MHz)通過感應線圈産生交變電磁場。當氩氣通過石英炬管時,交變磁場使氣體中的自由電子加速運動,通過碰撞電離形成自持放電的等離子體焰炬。這種能量傳遞方式無需電極接觸,故稱"電感耦合"。
等離子體特性
在10,000K高溫下,氣體高度電離形成電中性的離子-電子混合體。其特殊環狀結構分為:
炬管結構
三層同心石英管設計:
能量維持
通過渦流效應實現能量持續輸入:高頻電磁場誘導等離子體内部産生渦電流,電阻加熱效應使氣體保持電離狀态。

電感耦合等離子體(Inductively Coupled Plasma,ICP)是一種通過高頻電磁場電離氣體形成的等離子體,具有高溫、高能量密度的特性。以下從定義、原理和應用三方面詳細說明:
ICP通過電感耦合方式産生:将惰性氣體(如氩氣)置于高頻線圈産生的交變磁場中,氣體分子被電離形成等離子體。這種等離子體溫度可達6000-10000K,能夠高效分解樣品中的元素并激發其發光。
例如,ICP常與發射光譜(ICP-OES)或質譜(ICP-MS)聯用,進一步提升檢測精度和範圍。
