引言在发射光谱分析中,电感耦合等离子体(ICP)已被作为激发源广泛应用于测定各种物料中的微量和超微量元素,其部分原因是它容易获得、操作方便、动态线性范围宽、探测限低、样品分析效率高、固有的多元素分析能力、抗干扰能力强,以及分析准确度和精度都较好。常规的ICP如图1所示。它源于六十年代末,七十年代初由Greenfield和Fassel独立地发展为发射光谱的激发源,但直到1975年才
Introduction In emission spectroscopy, Inductively Coupled Plasma (ICP) has been widely used as an excitation source in the determination of trace and ultra-trace elements in various materials due in part to its ease of availability, ease of operation, wide linear dynamic range, Low detection limit, high sample analysis efficiency, inherent multi-element analysis capability, strong anti-interference ability, and good analysis accuracy and precision. The conventional ICP is shown in Figure 1. It originated in the late sixties and early seventies by Greenfield and Fassel independently developed as the excitation source of the emission spectrum, but only until 1975
