What Is a Component Analyzer?
A component analyzer is a device that can measure the type and amount of elements present in materials and parts.
Various analysis methods are available depending on the target material or part and the type of element to be detected. By selecting the appropriate method, a highly accurate and sensitive analysis can be performed. Some instruments can be applied not only to solids but also to liquids and gases.
Major analysis targets include medical and pharmaceutical products, metallic materials, organic and polymer materials, food, electronic materials, and various environmentally regulated substances.
Applications of Component Analyzers
Component analyzers are used not only to determine elemental content in the development of new materials and new pharmaceuticals but also to check for the contamination of impurities and hazardous substances.
They are also used to determine what elements are attached to parts when quality or manufacturing problems occur, to inspect foreign substances in products, and to analyze odors.
Component analyzers are also used in environmental analysis for nitrogen oxides (Nox) and carbon dioxide, which are indicators of air pollution, as well as for compliance with RoHS regulations, which have recently become more stringent.
Principle of Component Analyzers
Analysis using component analyzers requires knowledge and experience in each specialized field. Although it is possible to purchase analyzers and perform the analysis, there are various methods for analyzing the same substance, and the parameters to be set for the analysis are very complex. Therefore, it is common for this type of analysis to be outsourced to specialized companies.
Methods for analyzing components include the use of liquid chromatography for purity and impurity analysis of solids that dissolve in liquids or general-purpose solvents. Additionally, FT-IR is used for the chemical structure analysis of solid substances. For solids, there are many methods, such as spark emission spectrometer (ICP), X-ray fluorescence spectrometer, absorption spectrophotometer, FTIR, and mass spectrometer, depending on the element to be measured.
Some industries are required to comply with the RoHS Directive, an environmental regulation for export to Europe. Therefore, it is more efficient to request analysis from a vendor that can handle RoHS compliance.
