Polymer characterisation-  Spectroscopy FTIR,NIR, Raman, UV/Vis, NMR (access)

-  Chromatography (preparative GPC/HPLC, HPLC-PDA-MS, GPC-UV-DRI-Visco-LS, GPC High Temperature and triple detection, GPC-MS, TREF- Temperature Rising Elution Fractionation, GEF - Gradient Elution Fractionation, GC-PID, GC-MS, pyrolysis GC-MS)

                                              -  Mechanical and thermomechanical analysis (bending, compression and tensile test, modulus of elasticity, abrasion and scratch test, hardness, structural and surface characterisationcreep test, Charpy and Izod impact test, HDT/VICAT, DMA)

-  Thermal analysis (TGA, muffle furnace, DSC, moisture analysis, TMA (access), Flash DSC (access)

-  Structural and surface characterisation (particle size, porosimetry BET, XRD, roughness, permeability, surface wettability, optical microscopy, FEG-SEM-EDX, EELS-TEM, cryo-ultramicrotomy)

                                              -  Rheological analysis (rotational and capillary rheometer, viscometers, Melt Flow Index)

odour characterisation-  Optical analysis (transmission, reflection, refractive index)

-  Characterisation of barrier properties against odours and VOC

-  Odour characterisation (sensory room, dynamic olfactometry at detection threshold with human assessors, expert panel, GC-MS Sniffing)
