Microcalorimetry uses a suite of techniques to directly measure enthalpy and heat capacity changes that arise when chemical reactions occur. In aqueous solutions, heat flux into or out of the sample almost always happens on reaction. These reactions may involve a wide variety of situations, e.g., the interaction of two molecules (such as a cyclodextrin and its guest), changes in the conformation of complex macromolecules (such as proteins or DNA), or even in the structure of very complex multimolecular colloidal drug delivery systems (such as liposomes).

Calorimetry

Calorimetry measures the heat of transformation of a material subjected to a temperature variation in a controlled atmosphere.
Various systems are available: isothermal, isoperibolic, adiabatic, reaction, titration, solution, drop, Calvet-3D Sensor Inside, etc.

DSC / DTA

DTA - Differential Thermal Analysis - & DSC - Differential Scanning Calorimetry - measure, respectively, the temperature difference and the heat flow difference between a sample and a reference material (subjected to the same temperature variation in a controlled atmosphere).
DTA detects any change in all categories of materials; DSC determines the temperature and heat of transformation.
SETARAM Instrumentation offers:
- the widest temperature range of all DTA systems (from –150°C to 2400°C°) using high-precision tri-couple probes;
- the most complete choice of DSCs (from Q&C system to the highest sensitivity DSC, and 3D-Sensor Inside DSC).
Properties measured by DTA / DSC include phase changes, glass transition, melting, purity, evaporation, sublimation, crystallization, pyrolysis, heat capacity, polymerization, denaturation / aggregation, compatibility, etc.

High Pressure DSC & Calorimetry

With a high pressure DSC (or calorimeter), users are able to investigate materials and reactions under pressures as high as 1000 bars! In our solutions, the analysis chamber containing the sample (vessels, crucibles)is the only part under pressure. We have designed a gas panel capable of working under hydrogen (in compliance with ATEX regulation).

TGA

Thermogravimetry (TGA) measures weight changes in a material (subjected to temperature variation in a controlled atmosphere).
All SETARAM Instrumentation's balances satisfy the highest accuracy and stability criteria.
Properties measured by thermogravimetry (TGA) include corrosion, pyrolysis, adsorption / desorption, loss of solvent, oxidation / reduction, hydration / dehydration, decomposition, carbon black, etc,.

STA or TGA - DSC / DTA

For TGA-DSC, a DSC probe is attached to the balance to perform simultaneous TGA (thermogravimetry) and DSC (Differential Scanning Calorimeter) analysis of the same sample.
Simultaneous TGA and DSC measurements - STA - offer more information than separate measurements with two different systems.
SETARAM Instrumentation's range includes unique high temperature systems up to 2400°C and innovative coupling between symmetrical microbalance and 3D-Dimension DSC.

TGA coupled with QMS or FTIR

Coupling of a gas analyzer (QMS : Quadrupole Mass Spectrometer, FTIR : Fourier Transformation Infrared Spectrometer, GC : Gas Chromatograph, etc.) to the TGA (Thermogravimeter) facilitates identification of emitted vapors and understanding of transformation mechanisms.
SETARAM Instrumentation has developed several systems to optimize coupling between TGA (Thermogravimetry) and gas analysis:
- SuperSonic System offering unparalleled measurement capabilities for TGA coupled to MS.
- Capillary System to simplify your TGA-MS and TGA-FTIR measurements.
Our thermal analyzers have also been successfully coupled with GC, BET, or X-Ray apparatus.

Our unique high performance gas sorption instruments are designed to deliver the most advanced, reliable, and fully automated measurements, over wide range of pressures and temperatures. All products are made of the highest quality components, and are operated with a sophisticated, yet user-friendly LabView® control software. This guarantees the highest performance equipment available today.


Our products combine a state-of-the-art design with over 30 years combined experience in hydrogen research and instrumentation. Automation speeds up the time-consuming processes of sample evacuations, calibrations, data collection, and graph generation. Interactive controls and real-time data analysis is a powerful advantage of our products. Logical feedback control of pressure and temperature provides more detailed data than found in manual or simple automated Sieverts apparatus. This ensures consistent and reproducible measurements, providing the highest quality data while saving you time.

TMA

ThermoMechanical Analysis - TMA - measures the deformation of a sample under non-oscillating stress against time or temperature, with programmed temperature.
The vertical design of SETARAM Instrumentation's TMA systems makes it possible to work with very low loads applying only negligible force to the sample.
Properties measured by ThermoMechanical Analysis -TMA -include thermal expansion coefficients, softening, sintering, glass transition, etc.

TSC

This thermal analysis method, unique to SETARAM Instrumentation, uses MOLECULAR MOBILITY to access structural information that cannot be obtained by any other technique. It also gives access to dynamic parameters (∆H, ∆S and relaxation time t).
Properties measured by TSC include polymorphism, crystalline / amorphous rate, purity, glass transition, relaxation phenomena, etc.

Thermal conductivity and diffusivity are the most important thermophysical material parameters for describing the heat transport properties of a material or component. SETARAM offers a brand new Thermal Conductivity Analyzer TCi from its Canadian partner C-Therm Technologies Ltd.

Humidity is known to significantly affect the stability of many materials . SETARAM has developed the WETSYS controlled humidity generator to evaluate these effects.

σs

The magnetic specifications of ferromagnetic compounds can vary widely as a result of mechanical and/or thermal treatments. Specialists make us of these variations in magnetic specification to study the evolution of some solid state transitions. Magnetic measurements offer high sensitivity and allow the detection of very subtle metallurgical events.

CALISTO is a NEW softWare developed for Thermal Analysis applications from DSC, TGA, TMA and Calorimetry.

SETARAM Instrumentation and AKTS Software have formed a partnership to provide a global solution for kinetic analysis and determination of the thermal stability of materials.
