The main techniques include

• Calorimetry – chemical reaction energies

enthalpies (microcalorimeter, DSC)

• Chromatography – separation and quantification

of components on the molecular level

(GC, HPLC, SEC)

• Diffractometry – nanostructures, crystalline

materials (XRD), thin-film analysis (XRR),

pore and particle sizes (SAXS)

• Goniometry – contact angle,

dynamic wetting (surfaces/liquids)

• Light scattering – particle size distributions

• Microbalance – interactions and kinetics of

adsorption/desorption (QCM-D)

• Microscopy – AFM, EFM, LMF, SPM, torsional

harmonic AFM, optical, SEM/EDS, TEM

• Osmometry – osmotic pressure of solutes

• Rheometry – fluid deformation dynamics

(viscosity, elastic and viscous particle

interactions)

• Sorptometry – surface area, porosity

• Spectrometry – atomic level structures,

functional groups (MS, FTIR, UV-VIS,

TOF-SIMS, XPS)

• Tensiometry – surface tension (liquids)

• Thermogravimetry – thermal reactivity,

chemical composition (TGA)

• Electrokinetic properties –particle charge
