Helium-Pycnometer Pycnomatic ATC

The Pycnomatic ATC represents a full-automatic device for materials characterization in terms of volume and density measurements. It applies the technique of helium displacement to measure the real density of porous solids and powders. Due to the thermostatic control and the maximum pressure deviation of less than 0.01 mbar you can get results within an accuracy of 0.01% of the sample volume.

Inverse gaschromatograph Perkin Elmer Clarus® 580

The Device Clarus® 580 is a high-quality gas chromatograph from PerkinElmer®. Two parallel arranged columns allow simultaneous measurements of two different samples under the same conditions. Within the temperature range of 10°C up to 450°C it is also possible to use high boiling probe molecules. The available Adscientis SARL software allows to use your own samples as column material with the principle of the inverse gas chromatography. This way you can characterize the physico-chemical properties of unknown materials. The IGC has the power to determine some of the properties which are more difficult to measure such as surface energies, surface acidity/basicity/polarity, diffusion kinetics, surface heterogenity and nanoroughness.

Mercury Porosimetry

With maximum pressures of 4000 bars, pores ranging from 3.6 nm up to 1 mm can be characterized by our mercury intrusion porosimeters PASCAL 140/440 (Thermo Fisher) and the Poremaster 33/60 (3P Instruments). The method is particularly suitable for ceramics, sintered metals, very hard materials and in general for all solids exhibiting porosity in the nano- to micrometer range. The Pascal method automatically determines the correct pressure increase rate with respect to the pores to be examined, hence eliminating dead times during the analysis. The Poremaster, on the other hand, permits the setting of well-defined dwell times at a specific pressure and thus a very precise intrusion in certain pressure ranges. Moreover, pores with diameters from several 100 µm up to 1 mm can be characterized on this instrument.
