现代分析测试技术在印染行业的应用(十)——电感耦合等离子体(ICP)分析技术及其在纺织工业上的应用(1)

简要回顾了电感耦合等离子体（ICP）分析技术的发展历程，重点介绍了ICP技术的原理，包括ICP设备的作用原理、ICP光源的激发机理、ICP温度分布的不均匀性，ICP的环形结构和趋肤效应等。目前纺织品检测中常用的ICP分析仪器有ICP-OES（光谱仪）和ICP-MS（质谱仪）两大类，介绍了这两类系统中的高频发生器和样品引入系统，以及ICP应用中的干扰问题。采用ICP技术测定纺织品中的重金属含量，具有操作简单、测试精度高和重现性好的优点。

Application of modern analytical testing techniques to dyeing and finishing industry (Ⅹ)——ICP analysis technology and its application to textile industry (Ⅰ)

The Inductively Coupled Plasma(ICP),as optical spectrum light source,was electrodeless discharging plasma produced by electromagnetic induction under the frequency of 27.12 MHz or 40.68 MHz.In this paper,the development of ICP analysis technology was simply reviewed.The mechanism of ICP was briefly introduced,including action principle of ICP equipment,exciting mechanism of ICP light source,unevenness of ICP temperature distribution, ICP ring structure and skin effect etc.In textiles detection,common ICP analysis instruments are classified into two groups,that is ICP-OES(Inductively Coupled Plasma-Optical Emission Spectrometry) and ICP-MS(Inductively Coupled Plasma-Mass Spectrometry).High frequency generator,sample introduction system and interference problems in two systems were introduced.Finally,the ICP technology was applied to determine metal content in textiles,featuring simple operation,high precision and good repeatability.
