Usability:

TGA: To monitor thermal decomposition of materials, such as, for example, torrefaction or combustion of wood which quantifies the moisture content and the content of cellulose, hemicellulose, lignin, etc

FTIR: To the identification of substances and chemical bonds in a gas, but also in liquid / solid phase.

Application domains:

• Industrial – QA (quality assurance)/QC (quality control), Thermal Stability, Bio-polymers gases degradation

• Food – adulteration

• Environment – contaminated soil

• Pharmaceutical – residual solvent

• Unknown identification

• Decomposition studies

• Polymer QA/QC
