Surface area and surface porosity plays a vital role in various product development apart from it’s importance in research on functional material development. Central lab at LUMS has a state-of-the-art BET based surface analyzer Nova2200e Quantachrome (BET stands for Brunauer–Emmett–Teller theory). It performs a fully automated multi-point BET analysis on a variety of samples from powder to porous materials.
Possible Applications:
Pharmaceuticals: The useful shelf life and the dissolution rate of drugs depend upon the surface area and porosity of the materials. It also plays an important role in the purification and processing of the drugs.
Activated Carbons/carbon black – Surface area of carbon affects the performance of tyres. Likewise, properties of carbon used in gas masks, skin care, water purification, inks, laser printers and copier are greatly influenced by their surface area and porosity.
Paints and Coatings – The surface area of the pigment or filler affects the gloss, texture, color, color saturation, brightness, solids content, and film adhesion properties. Porosity also controls fluidity, drying or setting time, and film thickness.
Catalysts– Surface area and porosity affects mass transport phenomena in solid catalysts used in fertilizer industry, fuel cells and petrochemical industries.
Materials– Characterization of zeolites, carbon nanotubes, carbon nanofibers, MOFs, ceramics, fillers, desiccants, explosives etc.
