The Accelerating Rate Calorimeter and High Sensitivity
The ARC is the World Benchmark Adiabatic calorimeter to study energetic materials‌ Onset, Compatibility, Decomposition can all be studied.
But knowledge of the onset of heat release from energetic materials is of vital importance and here the HIGHEST sensitivity is needed, the ARC can be used to detect heat release at 0.001C/min and lower as the information here shows‌.
Data
Energetic Materials Explosives
Standard ARC Test With 3C steps Showing the exotherm starting and reaction below the onset
Now the quality data – only from the esARC from THT Very important for studying Energetic Materials 1C steps and onset at 0.002C/min Some heat from 105C (?) onset at 107C THT would challenge any other manufacturer to replicate this test and compare data!!!!
At 101C, no reaction - temp constant to 0.001C over 100 minutes
At 104C, some reaction - temp rise of 0.008C over 100 minutes (0.00008C/min) Only the esARC could determine onset of reaction of Energetic Materials at such sensitivity!
At 106C the self heat rate is 0.001C/min – easily detected by the esARC
