This consists of instruments for thermogravimetric
analysis, that is the technique which allows, by means
of a high-precision balance, determining changes in
weight in relation to time and temperature, by immerging
the sample in a controlled gasseous atmosphere.
It allows detecting oxidation and decomposition reactions
and obtaining information regarding the composition
and stability of the material.
Furthermore, the MTGA mode allows estimating the decomposition
kinetics by measuring the activation energy, while
the Hi-Res mode also allows separating events with
very similar decomposition temperatures, as it can
often be noticed in the analysis of high performance
This consists of a high performance instrument that
measures the temperature and the heat flux associated
with the transitions that take place in a sample in
a controlled atmosphere as a function of time and
This technique is widely used to determine temperatures
and melting enthalpy, glass transitions and the estimation
of the crystallization kinetics of polymers.
Working in modulated mode (MDSC), it is also possible
to separate very similar or overlapping thermal events,
measure the specific heat in almost isothermic conditions
at various temperatures, the diffusivity and thermal
ATR (Attenuated total reflectance) is a technique
which allows obtaining spectrums that carry information
regarding the surface of the polymeric sample through
direct physical contact between the sample and a crystal
through which the infrared radiation passes.
ATR analysis is therefore useful to reveal additive
migrations, oxidations or degradations that usually
take place in the part most exposed to solar radiation
and to atmospheric agents.
EDP-XRF - X-Ray Fluorescence Spectroscopy
This consists of an energy-dispersion spectrometer
which uses polarized X-ray fluorescence to reduce
scattered radiation improving the spectral resolution
at low concentrations.
The primary X-rays expel electrons from an atom from
its inner orbitals (core), creating electron holes
that can be filled by electrons belonging to external
This process releases energy in the form of X radiation.
The energy of the latter, being related to the energy
of the orbitals of the atom involved, makes the XRF
technique one of the best means for the qualitative
and semiquantitative determination of elements in
This non destructive analysis allows, in approximately
20 minutes, verifying the conformity of raw materials
and of finished products with the requirements imposed
by European Regulations, in particular by Dir. 2002/95/EC
(RoHS), 2002/96/EC (WEEE) and 2002/53/EC (ELV) for
the analysis of heavy materials and bromine.
Moreover, it is very useful for the quality control
of high-purity raw materials e.g. nanofillers for
the electronics industry.
The diffraction spectrum obtained when
a laser beam passes through a suspension of solid
particles in a liquid is dependent on the dimensions
of the particles and the distribution of their sizes.
The dimensional characteristics of the fillers used
in plastic materials have a great influence on both
the properties of the final compound, and in the production
The ability to measure the granulometric distribution
in powders is essential to Quality Control and project
Microscopic analyses are supported by modern image
scanning systems, allowing the study of the compound's
morphology and the gathering of more in-depth insight
into the problems related to defects in moulded parts.
One example is the study of the correlation between
mechanical decay and the variation of the distribution
of reinforcing agent lengths during production.
