SENSYS evo DSC (differential scanning calorimetry)

the highlights

An innovative line of Thermal Analyzers (-120 / 830°C) with 3D-Inside technology: DSC, High Pressure DSC, Robot DSC, TG – DSC – coupling to gas analyzer


  • Incomparable precision: the unique 3D sensor totally surrounds your sample and reference crucibles so that the entire energy of any transformation is monitored thereby giving you an unequalled accuracy of measurement.
  • Ease of operation: dedicated market leading CALISTO software that is not only intuitive but powerful enough to perform every typical experiments and data treatment.
  • Parameter Independent Calibration: because of the 3D transducer the calibration of SENSYS evo is independent of:
    – mass and form (powder, fibre, liquid, etc.) of the sample,
    – contact between the sample and the transducer,
    – crucible type,
    – sweeping gas (inert, oxidizing, reducing, wet, pressure) and flow rate.
  • DSC measurement under High Pressure: Two models of sealed “High Pressure”
    Crucibles are available in which only the sample and not the sensor is pressurized, thus allowing for the calibration, baseline and sensitivity to remain unchanged.
  • Large sample volumes: The working volumes of the crucibles (up to 250 μl) are highly suited to the study of heterogeneous samples, or low-energy phase transitions. They are intended for analyses where the pressure generated by the sample remains low. Crucibles are available in alumina, aluminium, rhodiated platinum.

2D plate-shaped or cylindrical 3D Calvet sensor?


Coupling to a BET system
An option was developed to detach the SENSYS evo DSC sensor from its base and to connect it to additional instrumentation. As an example, this was used to couple a BET system to a DSC, and thus measure gas sorption enthalpies.

Operations under supercritical CO2 conditions
This new option is based on a high pressure cell connected to a high pressure syringe pump. The entire line, from the pump to the cell, was designed to be heated up to above 31 °C, i.e. above the CO2 critical temperature.

Panel for gas flow under high pressure
A high pressure gas panel allowing one to flow a gas in a bitube cell, is now available. The maximum operating pressure is 100 bar and maximum temperature is 400 °C. It is based on a high pressure syringe pump, and two precision controlled backpressure regulators for the 0-7 and 0-100 bar ranges.

From routine QC to the determination of a complex formulation within R&D, a robotic autosampler is the ideal solution when high sample throughput is essential.

The SENSYS evo DSC Robot offers the possibility of performing unattended analysis of up to 48 samples.

The SENSYS evo DSC robot is the only automated DSC capable of working with high pressure Incoloy crucibles.

– Vertical SENSYS DSC evo
The vertical configuration of SENSYS evo DSC is particularly suitable for studying the adsorption of gas on catalysts. Using a specific silica reactor inserted into the calorimetric block, measurements on heats of adsorption are obtained with a very high level of precision.

The unique 3D-Sensor can be combined with a symmetrical balance beam. The performances of the SENSYS evo TG-DSC result from the absolute symmetry of this unique system in which the TG and DSC transducers, which are mechanically independent, retain their specific characteristics.


With its high precision and wide temperature range (-120 to 830 °C) the SENSYS evo DSC has a wide range of applications, especially in the fields of thermodynamics (Specific Heat Capacity Cp precision within +/-1 %), pharmaceuticals (phase diagram, polymorphism, purity, thermal stability), safety of chemical process(transition, decomposition under high pressure), energy(catalysis, hydrogen storage, hydrogen adsorption), polymers (glass transition, measurement under pressure), etc.
