Advantages of the HSSET System
HSSET system is an integrated instrument comprising a suite of measurement capabilities. It allows for research under conditions out of the analysis range of modern thermographical and calorimetrical equipment. In particular, the HSSET instrument is exclusively capable of mapping distinct temporal-thermal pathways, and operating in a wide controllable range of reaction environments spanning from vacuum to high gas pressure settings. Due to its high performance and high speed design, the HSSET setup allows the study of transients derived from discontinuous or rapid impulse changes in process parameters. Such capability allows the use of the HSSET system to evaluate and assess a chemical and thermal system’s response to extremely rapid changes in process parameters, which may contain significant information about the reaction mechanism under study and consequently allow for much more efficient process optimization.
