Infrared spectroscopy of the regenerated mineral insulating oil

Abstract

Infrared spektroscopy is a measuring technique using different material ability to absorb the frequence of IR ray. Based on absorbed (or passed through) frequency spektrum, it is possible to determine different chemical compounds, molecular structure in the sample and their changes in consequence of ageing process. There are several measuring techniques of Infrared spectroscopy. Attenuated Total Reflectance technique (ATR) and measuring in transmission mode are the most widely used ones. The main aim of the paper is to demonstrate the difference in the results of different techniques of infrared spectroscopy and determine the way of interpretation of obtained spectra.
