FEI - Quanta 200FEG
Our Quanta 200 FEG (FEI) scanning electron microscope (SEM) was installed at CIC EnergiGUNE in the winter of 2010. It is a high resolution environmental microscope capable of running in 3 different modes: high vacuum, variable pressure and environmental modes, which means that it can handle all specimens even uncoated, non‒conductive samples as well as wet samples that require being above the vapor pressure of water. The combination of high output thermal field emission (> 100nA beam current) with a high sensitivity (18 mm) allows get final resolution until 3‒5 nm. The presence of a backscatter detector also will allow us measure electronic properties like the atomic contrast in our samples. The working voltages of the Quanta 200 FEG (FEI) scanning electron microscope vary between 3kV (low vacuum mode) and 30 kV (high vacuum mode). One key of our Quanta 200 FEG (FEI) SEM is that is it possible work at very low electron probe energies providing images of samples exhibiting low conductivities.
NETZSCH - STA 449 F3 system connected to QMS 403 Aëlos and DIL 402 C/4/G by NETZSCH
The NETZSCH STA 449 F3 Jupiter® is a robust, flexible, easy-to-operate instrument for determining caloric effects (transformation temperatures and enthalpies) and mass changes at the same time.
Simultaneous Thermal Analysis (STA) generally refers to the simultaneous application of Thermogravimetry (TG) and Differential Scanning Calorimetry (DSC) to one and the same sample in one instrument. Additionally, the system is connected to a Quadrupole Mass Spectrometer (QMS) in order to analyze gases, and in particular, volatile decomposition products of thermal analysis.
The STA allows the measurement of mass changes and thermal effects between -150°C and 2400°C, using various interchangeable sensors and furnaces. Different possible pump systems aswell as the optional mass flow controldevice allow measurementsunder well-defined atmospheres.
DSC analysis allows studying melting/crystallization behavior, solid-solid transitions, polymorphism, degree of crystallinity, glass transitions, cross-linking reactions, oxidative stability, purity determination, specific heat and thermokinetics. TG analysis allows studying mass changes, temperature stability, oxidation/reduction behavior, decomposition, corrosion, composition and thermokinetics.
