Studies of Techniques for Analysis of Photocopy Toners by IR

CODEN: JFSCAS

Abstract

A study was undertaken to examine three measurement techniques for the analysis of photocopy toners by microscopical infrared spectrometry (IR) and to compare these techniques to studies previously done by Diffuse Reflectance (DR). Based on our preliminary studies, analysis of photocopy toners may be successfully performed by DR, microscopical Attenuated Total Reflectance (ATR) with a germanium Internal Reflection Element (IRE) or by microscopical Reflection-Absorption (R-A) techniques with a variety of reflecting media including mirrored slides, low emissivity glass, and aluminum foil. Selection of the analysis technique can be made based on equipment availability, budgetary constraints, ease of sample preparation, speed of analysis, and importance of the original photocopied document to determine if a mildly destructive technique can be used.
