Simultaneous techniques utilize the application of two or more techniques to the same sample at the same time. This technique has greatly improved the understanding of numerous materials. One of the most common forms of a simultaneous technique is the combination of thermogravimetry with differential scanning calorimetry or differential thermal analysis to produce a simultaneous DTA/DSC-TGA (SDT). This combination allows the weight and heat flow of a material to be monitored simultaneously. Another simultaneous technique that is widely used is the analysis of gaseous products, which is commonly referred to as evolved gas analysis (EGA). EGA usually employs a mass spectrometer or an infrared spectrometer combined to a thermal analysis instrument. This setup allows the gasses to be monitored as they are evolved. This article details the SDT and EGA techniques and provides references to more detailed descriptions.
