The document discusses the development of photocalorimetry techniques for solid state analysis. It outlines some key challenges with current stability and photostability studies on pharmaceutical solids. The author plans to use a Thermal Activity Monitor (TAM) calorimeter to study the photodegradation of samples in a controlled light environment. Some planned work includes validating the system using a model triacetin reaction, comparing glass and stainless steel sample containers, and examining the effect of fill volume on calorimetric output. The overall goal is to develop a versatile photocalorimetry testing system for pharmaceutical materials.
