Analysis of Inorganic Additives in Resin by FTIR and EDX

The approach taken in the analysis of additives is dependent on whether the additive is organic or inorganic. Organic additives are typically identified by first extracting the additives using a suitable pretreatment procedure, and after chromatographic separation of the extracted components, a suitable analytical instrument is used for qualitative analysis. On the other hand, comprehensive identification of inorganic additive components is typically based on the results obtained using elemental analysis, infrared spectroscopy or morphologic observation, etc.
Here, we introduce examples of FTIR analysis to obtain useful information regarding some typical inorganic additives, in addition to an example of analysis of a resin containing an inorganic additive using FTIR and EDX.
