Introduction

The micro reaction calorimeter μRC from Thermal Hazard Technology (THT), performs isothermal, step-isothermal, temperature scanning and titration studies as well as having the capacity to stir liquid reaction media. Options for pressure measurement, solid addition and gas flow are available.

The small sample requirement (up to 1.5ml) permits rapid temperature changes because the relatively small heat sink reaches thermal equilibrium very quickly. A stable baseline and temperature change is typically achieved within 20 minutes. The μRC Peltier modules control the sample temperature over the temperature range of –20 to 170°C requiring no external chillers or liquid nitrogen cooling.

Applications

• Heat capacity determination

• Process development

• Thermal stability 

• Enthalpy of solution by solid addition

• Hydrogenation and gas flow

• Simultaneous titraiton and pressure measurement
