SENSYS evo TG-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 The HIGHLIGHTS
Differential Scanning Calorimeter
• Incomparable precision: the unique 3D DSC 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.
• 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.
Thermogravimetry
• Excellent TG signal baseline: the symmetry of the microbalance, with its sample and reference suspended vertically from the beam guarantee reproducible positioning of the sample over time and excellent stability of the TG signal baseline.
• Automatic compensation of Buoyancy: the sample and the reference are heated inside the same calorimetric block (symmetrical furnace), which means that the buoyancy effect is automatically compensated.
Ease of operation: dedicated market leading CALISTO software that is not only intuitive but powerful enough to perform every typical experiments and data treatment.

Crucibles of 150 µl capacity are available in aluminium, alumina, platinum or silica to suit the chemical nature of the sample. A silica tube can be added to protect the transducer and the analysis
chambers during test involving sweeping with corrosive gas.
Evolved Gas Analysis
The SENSYS evo design features both a small furnace volume and also an easily accessible exhaust to allow for direct connection to further analysis devices such as MS, FTIR, GC etc. without
excessive sample dilution or long transfer lines. Setaram offers a range of transfer lines and software solution for system comprehensive integration.
To date SENSYS has also been successfully coupled with:
• FTIR/MS and GC,
• Gas Sorption devices,
• An X-ray absorption spectroscopy apparatus.
Measurements under controlled humidity
Humidity is known to have a significant influence on the stability of many materials. In order to evaluate this specific influence, SETARAM has developed WETSYS a controlled humidity generator. It can:
- deliver a very precise level of relative humidity (RH) from 5 to 95 % depending on the temperature and measure the humidity around the sample.
- be connected to SETARAM instruments, and in particular to the SENSYS evo TG-DSC as well as other analysis instrument(RX, GC, etc.) for studies of sorption, hydration, stability, etc.

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 3D DSC SENSOR
The sample and reference sensors are composed of 120 thermocouples mounted in a cylinder that totally surrounds the measurement zone. These two cylinders can measure up to 94 % of all heat exchanged with the sample / reference, as compared to 20 % typically (50 % absolute maximum) with 2D place sensors.
The sensors are mounted in a calorimetric block that is further water cooled to eliminate any environmental variations and therefore giving you a highly precise and robust sensor with a unique level of specific sensitivity.
For studies at sub-ambient temperature, an automated cooling device utilizing evaporation of liquid nitrogen can be fitted onto the calorimetric unit.
Simultaneous TG & DSC
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:
• symmetry of the furnace: the sample and the reference are heated
inside the same calorimetric block, which means that the buoyancy effect is compensated automatically.
• symmetry of the upper beam microbalance: its vertical design with
beams of identical length guarantees perfectly reproducible positioning of
the sample over time and excellent stability of the TG signal baseline.
The SENSYS evo TG-DSC is an extremely sensitive instrument that can
measure actual variations in weight of the order of one microgram.
Gas control panel
The SENSYS evo TG-DSC incorporates an automated gas control panel.
It is possible to:
• select from 3 different carrier gases (flow rate: 4 to 200 ml/min)
• mix one of these carrier gases with another "auxiliary or reactive" gaseous fluid
(flow rate:0.3 to 16 ml/min).
