Application with the ARC Module
DTBP
DTBP (Di-tert-butyl peroxide) is the commonly used standard substance to
carry out ARC measurements. The plot shows the thermal runaway reaction of 20% DTBP in toluene, accompanied by
the pressure increase after 600 min.
DSC-like Testing: Application of the Modul with External Heater
KNO3
Potassium nitrate (KNO3) is used for the synthesis of gunpowder (sulphur, char and KNO3). It is also used in food preservation (E252) and as an important potassium- and nitrogencontaining fertilizer. The measurement was carried out in scanning mode with a constant power input of 200 mW. Two endothermal effects at 129°C (peak area of -45 J/g) and at 334°C (-87 J/g) are related to phase transitions.

ANFO
Ammonium nitrate fuel oil (ANFO) is a mixture of solid ammonium nitrate and
mineral oil. Easy handling allows it to be used safely in mining, stone quarrying, and tunnel construction. The basic
reaction during detonation is the decomposition of the hydrocarbon and the ammonium nitrate into CO2, nitrogen and water. For this test a mixture of NH4NO3 and toluene was used. Three phase transitions (endothermal peaks) up to 150°C and the large exothermal decomposition peak starting at approx. 235°C can be detected.
Application of the VariPhi™ Module
Reliable Specific Heat
An advantage of the VariPhi™ heater is the ability to easily determine cp values of liquid and solid materials. Measured here are three liquids over a temperature range from room temperature to 90°C and 115°C.
Application of the VariPhi™ Module
Compensated Φ-Factor
The mass of the container can be completely compensated for when VariPhi™ is used. This allows for either an adjusted Φ-factor – similar to the real reaction vessel of a plant – or for an ideal Phi factor close to the value of 1.
