Particle Characterisation

• Particle sizing by laser diffraction (Malvern Mastersizer 2000/3000)
• Nanoparticle sizing using dynamic light scattering
• Zeta potential by electrophoretic light scattering
• Sizing larger particles using sieving (mechanical and airjet)
• Morphology analysis of particles using quantitative image analysis
• Emulsion stability using LUMiSizer technology
• Specific surface area using gas sorption
• Single particle ICP-MS

Powder Characterisation

• X-Ray powder diffraction (the gold standard technique for physical form identification) using a Bruker D2 phaser benchtop system with a copper anode X-Ray tube
• Density (tapped/bulk for powders, displacement and cup for semi-solids, Stable Microsystems Volscan for porous materials)
• Powder flow and rheometry using Brookfield shear cell and FT4

Microstructure

• Internal 3D non-destructive structural analysis using X-Ray Microtomography (XMT)
• Imaging using microscopy (light, confocal and SEM) and quantitative image analysis
• Fracture and deformation using texture analysis
• Large and small deformation analysis using rheological testing

Thermal

• Thermal analysis of melting points, degree of crystallisation, glass transition temperature and specific heat capacity using DSC and TGA

Chemical Analysis

• Moisture analysis (Karl Fischer, water activity and dynamic vapour sorption)
• Rapid screening methods using near infrared spectroscopy (NIR)
• Solid fat content using low resolution NMR
