This work illustrates how the Tandem micro-Reactor (TMR); when interfaced to a GC-MS; facilitates the rapid characterization of virtually any material: gases; liquids and solids. A TMR has two independently controlled micro-reactors in series. Each micro-reactor has three heating modes: isothermal (up to 900°C); multi-linear; (e.g; 100-400°C at 20°C/min) and distinct temperature steps (e.g; 100°C; 200°C; etc.). The TMR can be used for both Evolved Gas Analysis (EGA) and detailed component analysis. Three examples illustrate how the TMR-GC-MS can be configured to differentiate or identify virtually any material. (1) Lignin; oak; bagasse and cellulose are easily differentiated using EGA-MS - each material is analyzed directly by simply weighing the sample ( © 2014 Elsevier B.V. All rights reserved;
