Elastomers Vol 1 This applications booklet provides an introduction to the thermal analysis of elastomers with a large number of practical examples. The main techniques used for sample measurement are thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). In particular cases, thermomechanical analysis (TMA) and combined techniques (TGA gas analysis) have also been employed.

Food The application of Thermal Analysis (TA) to food technology is relatively new. In the past, thermal analysis was used, above all, as a standard method for the investigation of polymers. This booklet presents an overview of the main areas of application of thermal analysis: storage lifetimes or process parameters can be determined as well as interactions between food components. Every method, of course, requires a specific evaluation period before it can be routinely employed, during which time METTLER TOLEDO application engineers will be pleased to be of assistance.

EGA Evolved Gas Analysis This booklet provides an insight into two such so-called hyphenated techniques, TGA-FTIR and TGA-MS. The first part of the booklet focuses on basic principles and describes the techniques. It also includes a practical section and an introduction to the interpretation of spectra. The second part discusses different applications performed in our applications laboratory using TGA-MS and/or TGA-FTIR. Two additional applications illustrate the use of the rather unusual combination of TMA with MS.
