Дифференциальная сканирующая калориметрия (ДСК) / Дифференциальный термический анализ (ДТА) – SENSYS evo DSC

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

Эта система дифференциальной сканирующей калориметрии с 3D датчиком Calvet типа обеспечивает исключительную разрешающую способность и анализ образцов размером до 270 мкл. Это позволяет измерять характеристики самых разнородных образцов, определять теплоемкость с точностью до 1%, и использовать тигли с уникальными возможностями, включая работу с протекающими реакциями с непрерывным потоком и под высоким давлением. Уникальный датчик Calvet 3D обеспечивает высокое качество измерения параметров образца и не реагирует на давление. Таким образом, в ходе эксперимента на образец можно воздействовать различными газами, смесями, подвергать его воздействию контролируемого давления вплоть до 400 бар.

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.

Характерные особенности

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.


Области применения

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.
