The Highlights

High-performance Modular Thermo Mechanical Analysis (TMA) (ambient / 2400°C)

SETSYS Evolution is the standard for high performance TG, TG-DSC and TG-DTA application. It is based on a complete modular thermal analysis platform for
– TGA, DTA and DSC
– Simultaneous TGA/DTA and TGA/DSC
– Dilatometry/ Thermo Mechanical Analysis (TMA)
The key to the SETSYS TMA is the vertical design of its displacement transducer.
 
NEW PARTS AND OPTIONS
High temperature bending for TMA
A graphite-based, high temperature, 3-point bending accessory is available for work up to 2400°C+.

Protected thermocouple

An alumina sleeved protected thermocouple was designed to prevent corrosion/damage from the gases evolved from the sample. Various thermocouples types are available up to 1750°C.

FEATURES

Furnace
The SETSYS Evolution comes equipped with a robust and high performance graphite furnace, offering high scanning rates ( up to 100 °C/min across the entire temperature range) and fast turn around between experiments.
A SINGLE furnace covers all applications from ambient to 2400 °C . The maximum temperature operation is adjusted by simply and rapidly changing the control thermocouple (for 1000, 16000, 1750 or 2400 °C).
SETSYS Evolution provides also primary and secondary vacuum capabilities.
Atmospheres
A high-performance gas control panel equipped with MFC (Mass Flow Controllers) ensures a precise control of the atmosphere and of the gas mixtures.
Many possibilities are offered for the control of the atmosphere.
Standard SETSYS TGA Evolution configuration allow for any type of gas up to 1750 °C. Above 1750 °C, the furnace remains the same and a few accessories are replaced to allow operation up to 2400 °C.
Gas include H2, CO2, NH3 up to 100% concentration. Optional accessories are available for:
– ensuring hydrogen safety
– working under corrosive gas (allows evaluation of materials under 100% corrosive gas) – see the technical note TN679
– working under fluorine
– working under humidity – see the humid gas generator WETSYS (generates a humid carrier gas up to 90%RH at 70°C, can be used up to 1750°C, gases include Air, He, N2, CO2…, can program complex humidity profiles)

TMA displacement transducer
The key to the SETSYS TMA is its vertical design. The TMA probe is held by the electronic suspension so that:
– virtually no force is applied at high temperature
– there is no bending of the probe at high temperature
– for volumetric measurement on powders, sample can easily be put in the container.
In such a configuration the SETSYS TMA can detect very small dimensional changes and there is no need of long sample for accurate measurements.

Electronics & software
SETSYS Evolution comes equipped with Calisto
 
APPLICATIONS

For measuring variations in size of solids or powders, the SETSYS TMA is used for characterizing polymers and compounds (softening, glass transition, degradation, reticulation) under varied stresses, for studying films and fibers, for sintering ceramics, for studying the thermal behavior of alloys and more generally for measuring coefficients of expansion.
