Subambient thermal volatilization analysis

The differential distillation technique (also known as subambient thermal volatilization analysis (SATSVA) is a very simple technique which allows a rapid indication (both qualitative and quantitative) of small amounts of gaseous and/or liquid low molecular weight compounds which can be trapped and frozen at liquid nitrogen temperature [1439, 1440]. 

Subambient thermal volatilization analysis can also be used to probe the effects of physical fillers in silicone materials. In 2008 Lewicki et al. [51] studied the degradation profiles and product speciation of a series of montmorillonite clay filled silicone elastomers which had been characterized using SATVA. Shown in Figure 13.17 are a series of TVA thermal degradation profiles for the non-oxidative degradation of a bimodal-condensation-cured silicone matrix, filled with 0-8 wt% of organically modified montmorillonite (0-MMT) exfoliated nanoclay platelets.
