Analytical Pyrolysis of Paper by a Novel Thermal Slice Technique with a Pyroprobe

Abstract

This application note presents pyrolysis GC-MS of cash register paper, using a thermal slice technique to thermally remove the paper component from the analysis

Introduction
 

In a previous application¹, paper which is coated with material that changes color when exposed to heat, also known as thermal paper, was analyzed with evolved gas analysis (EGA) while including a thermal slicing technique to remove the cel- lulosic portion of the paper but leaving the additives and polymer coating. In this application, this technique was used in conjunction with pyrolysis-GC-MS.
