FaraPack Polymers: Analysis

FaraPack Polymers biedt toegang tot een uitgebreide reeks analysetechnieken waaronder enkele van de nieuwste instrumenten onder ontwikkeling bij de universiteit van Sheffield. Gekoppeld met gedetailleerde interpretatie door onze analytische wetenschappers kunnen materiaaldefectanalyse, vaststelling van moleculair gewicht, chemische samenstelling en het testen van mechanische eigenschappen snel en nauwkeurig worden uitgevoerd, zodat u een beter inzicht krijgt van uw materialen en processen, en om wanneer nodig effectieve oplossingen voor problemen te formuleren.

FT/IR: Infra-red spectra taken of two medical coatings.

Chemische samenstelling

Infrarood analyse: FTIR/ATR
NMR
Electrospray massaspectrometrie
ICP massaspectrometrie
Grote- en kleine-hoekstrooiing röntgenstraling

Example: FT/IR: Infra-red spectra taken of two medical coatings using attenuated total reflectance (ATR). The spectra obtained revealed that both coatings were polyurethane based, but importantly that one contained polyether based soft segments and the other polycarbonate based soft segments. This information enabled new coatings for the medical devices to be sourced by FaraPack Polymers which were resistant to hydrolysis and chemical attack (see figure above right).

Rheometer: Image of the TA instruments AR G2 rheometer.

Fysische eigenschappen

Testen hardheid (Shore, Barcol)
Differentiële scanning calorimetrie (DSC)
Thermo gravimetrische analyse (TGA)
Reologie (Viscositeit)
Contacthoeken
Dynamische mechanische thermo-analyse (DMTA)
Dynamische lichtstrooiing (DLS)

Example: Rheometer: Image of the TA instruments AR G2 rheometer equipped with cone and Peltier plate geometry. Equipment has been used to study the rhemometry of polyacrylate materials used as viscosity modifiers in printing inks and paints. In particular the viscosities of the polymers were measured and the shear-thinning and shear-thickening behaviours of the materials were investigated (see photograph right).

GPC chromatograms of two samples of PEEK.

Chromatografie

Hogedrukvloeistofchromatografie (HPLC)
Gel Permeatie Chromatografie (GPC)

Example: GPC chromatograms of two samples of polyetherether ketone (PEEK), a high performance thermoplastic that is difficult to analyse via GPC due to its chemical resistance, however, in this case a derivatisation process was employed by FaraPack Polymers which enabled conventional chloroform:methanol GPC to be used to calculate the molecular weights and polydispersities of the PEEK samples (see figure right).

EDAX SEM Microscope: SEM microscope coupled with an EDAX detector.

Microscopie en spectroscopie

UV/Vis spectroscopie
Fluorescerende spectroscopie
Confocal en optische microscopie
Fluorescerende microscopie
IR en Raman microscopie

Example: EDAX SEM Microscope: SEM microscope coupled with an Energy Dispersive X-ray (EDAX) detector. Operating in EDAX mode the microscope has been used to locate tracer elements which were incorporated into a polymer blend in order to understand more about the phase separation processes occurring within the polymer blends (see photograph right).
