Analysis of foreign substances and component analysis: Comparison of micro-Raman and FTIR.

We would like to introduce our "Chemical Analysis - Trust Us Service." When conducting component analysis of foreign substances or stains on products, it can be challenging to determine whether organic analysis or inorganic analysis is more suitable, and which specific analysis within organic or inorganic is the most appropriate. We provide a comprehensive service for customers who are struggling with the selection of analysis methods. Since each analytical instrument is capable of measuring different targets, it is necessary to choose the method that fits the purpose based on the information available.

This document introduces the characteristics of each spectroscopy method and the spectra obtained when comparing infrared spectroscopy and Raman spectroscopy. Both infrared spectroscopy and Raman spectroscopy are vibrational spectroscopies that investigate the vibrational energy of molecules, but the shapes of the spectra obtained from each method differ even when measuring the same substance. Infrared spectroscopy and Raman spectroscopy are complementary; by conducting both analyses, information that cannot be obtained through a single analysis can be acquired in a more detailed and accurate manner. For more details, please refer to the published catalog.

This is an introduction to the comparison between Raman spectroscopy analysis by Aites Co., Ltd. and FTIR. Spectroscopic analysis is suitable for component analysis of foreign substances and qualitative analysis. Both Raman and FT-IR can obtain spectra based on the structure of the analysis target. However, since each has its strengths and weaknesses, it is necessary to choose between the two depending on the analysis target.
