The Institute has a number of well-equipped laboratories, which allows to operate at various levels of the process of research and technological innovation.
The “Facilities” section of the website offers a complete and detailed tour of these valuable resources.
In addition to this, ICMATE wants to propose a journey that, from week to week, will lead to the discovery of its vast technology park.
This week's featured laboratories
The thermogravimetric and calorimetric analyses allow estimating the stability or degradation of a material/compound with temperature and to measure phase changes or conversion temperatures. The TA SDT Q600 instrument provides simultaneous measurement of weight change (TGA) and true differential heat flow (DSC) on the same sample from RT to 1.500 ̊C. TGA/DSC measurements can be performed under controlled atmosphere (dry air, wet air, nitrogen, carbon dioxide, argon, helium) with digital mass flow controllers. Secondary reactive gases (O2, Ar/H2 mixtures) can be carried directly on the sample. Recommended sample quantity is in the 3-20 mg range.
TGA/DSC analyzer can be connected to a residual gas analyzer (RGA) Hiden-HPR20 QIC with a capillary sampling system fitted to the purge exhaust gas exit of TA SDT Q600. The HAL 7 quadrupole scan range is comprised between 1 and 300 a.m.u., leading to the identification of gaseous compounds generated during the TGA/DSC scan.
There is also a dilatometer for the evaluation of shrinkage and / or expansion of pellets of standard size in the range 500 / 5000μm. The materials analyzed can be of various nature (polymers, glasses, ceramics, metals as bulk or powders). By varying the temperature (from room temperature to 1600 ° C with maximum ramp of 20 ° C / min) is recorded dilation and evaluated the coefficient of expansion. The measure of pellet bending and/or softening at high temperature is also possible.

Thermo-gravimetric or calorimetric analysis allows to investigate the sample behaviour as a function of the temperature. Important information can be obtained regarding the sample thermal stability, weight modification, oxidation and corrosion, degradation temperature, specific heat, melting enthalpy, phase transition etc..
The Netzsch STA 449C Jupiter® (Simultaneous Thermal Analysis) operative in IENI-CNR is a simultaneous thermos-analyser and provides Thermo-Gravimetric Analysis (TGA), Differential Thermal analysis (DTA) and Differential Scanning Calorimetry (DSC).
The analysed sample (few tens of mg) undergoes a pre-set thermal programme by the simultaneous thermo-analyser. The measured physical characteristics are the weight variation, the absolute temperature and the temperature variation with respect to a reference. All the parameters are collected at the same time.
STA 449C can operate over a wide temperature range from 25 to 1600°C in controlled atmosphere (air or nitrogen) in static or dynamic mode or in vacuum, thus operating in strictly controlled conditions also on sensitive samples.
