分析仪器是实验室的重要测试手段和主要工具。不仅石油、化工、农业、医药等传统分析领域需要分析仪器,其他科技领域亦越来越多地需要采用分析仪器解决分析课题。例如,半导体材料需要用红外光谱仪测定外延层厚度,金属材料需要作各种表面物理微区分析和元素成份的原子吸收光谱或等离子光谱分析,许多轻工业材料也需要用分析仪器进行剖析。 Analytical instruments are important laboratory test tools and tools. Analytical instruments are not only needed in traditional analytical fields such as petroleum, chemical, agriculture, medicine, but also in other fields of science and technology. Analytical instruments are also increasingly needed to solve analytical problems. For example, semiconductor materials require the use of an infrared spectrometer to measure the thickness of the epitaxial layer. Metallic materials require various surface-physical micro-area analysis and elemental atomic absorption spectroscopy or plasma spectroscopy. Many light industrial materials also require analysis by analytical instruments.
