一、成分分析（ICP、辉光放电质谱）
在半导体成分分析方面，有多种先进的表征技术与仪器。电感耦合等离子体质谱仪（ICP-MS）表现卓越，其超痕量元素分析性能突出，检测限低至 ppt 级别，擅长高精度检测半导体材料里的稀土、重金属等元素，常用于剖析高纯半导体材料中的杂质含量；辉光放电质谱仪（GDMS）同样出色，它能直接分析固体样品，免去繁琐前处理，对半导体材料杂质元素灵敏度高、剖析深入，可精准探测极低含量杂质，尤其契合高纯度金属及半导体材料的分析需求。
关于两中检测方法中用到的化学试剂，除了各种元素的标准品外，ICP-MS中还会用到一些校准曲线标准溶液、内标试剂、基体改进试剂等。百灵威供应检测过程中可用到的多种标准品及溶剂，品种齐全，纯度高，欢迎大家来选购。

二、结构分析（SEM TEM）
在半导体材料结构分析领域，透射电子显微镜（TEM）和扫描电子显微镜（SEM）作用显著。二者制样有别。TEM 要求样品极薄（10 - 200nm，高分辨 5 - 50nm ）以便电子束穿透，SEM 对厚度要求较松。TEM 样品稳定性要求高，常用铜网或支持膜处理；SEM 对软质易变形样品多采用喷金、喷碳增强稳定性。两者非导电样品都要导电处理，TEM 常给超薄切片喷碳膜，SEM 常用喷金、喷碳且注重厚度控制。化学试剂使用上，TEM 生物制样用戊二醛等固定、酒精等脱水、环氧树脂包埋、醋酸铀等染色；SEM 用乙醇等清洗杂质，生物样品用戊二醛等固定，非导电样品用金、碳做导电处理。

三、表面性质研究（液相，离子色谱）
在半导体分析领域，离子色谱与液相色谱都发挥着关键作用。离子色谱可高灵敏度检测半导体材料中的杂质离子，像金属离子与阴离子，还能分析表面吸附离子、评估材料在不同环境下的稳定性，是生产中把控质量的有效工具；液相色谱既能分离分析有机杂质，助力优化合成工艺，又可监测合成反应进程、剖析反应机理，还能联合其他技术分析纳米半导体材料粒径与分布，以及表征表面修饰情况，为半导体研究与生产提供全方位支持。接下来，我们将详细介绍液相 - 质谱联用和离子色谱测试中会用到的各类化学试剂。
