Description
Summary:This contribution reports the coupling of TG with FTIR, MS and GC-MS (Synergic chemical analysis). During thermogravimetric analysis the gases evolved are analysed using `real-time' FTIR and MS. Simultaneously the gases are collected on an absorbent trap (organic trap module, OTM) for subsequent analysis using GC-MS. As an example the technique has been used to identify the products evolved from a printed circuit board during thermal oxidation. The use of TG-FTIR-MS-OTM-GC-MS provided information that could not be available through single techniques alone. For example, it was possible to ascertain the temperature range over which bromophenol was released.
