Abstract
This application note presents evolved gas analysis of thermal paper, including using heart cutting technique to transfer selected group of compounds to sepa - rate sample pathway.
Introduction
Similar to the concept of thermogravimetry (TGA), Evolved Gas Analysis (EGA) is a method that uses precise temperature increments to first thermally extract and then decompose materials. The difference between TGA and EGA is that mass spectral data is produced in EGA relative to temperature instead of mass loss as in TGA, so more chemical information is gained.
