TGA-IR Interface (Evolved Gas Analysis)
Gas cell and interface between TGA and FTIR instruments for evolved gas analysis. Unique cell design, Flexible Heated Transfer Line (240C) and Dijital Control Unit
Combination of TGA and FTIR is a powerful technique for the evolved gas analysis during material heating under controlled atmosphere. Transferring evolved gas with a constant flow rate to the temperature-controlled IR-cell during the process will provide information about gas species while material is loosing weight. Gravity aligned quartz cell design and heatable transfer line makes this product highly resistant to corrosive gas environment and prevent water condensation
