Analysis of paint scrapings using an infrared microscope

Introduction

There are a number of ways of analyzing paint scrapings employing the FTIR. Measurement can be carried out by crushing the collected paint scrapings and employing the KBr pellet method or diffuse reflection method; or by measuring the surface of a coating with the ATR method; or by measuring the minute sample with an infrared microscope. Introduced here is an example of measurement of paint scrapings from a timber surface.
