1. Surface functionalization of cellulose fibers and exploration of its influence in ion exchange chromatography
University essay from KTH/Fiber- och polymerteknologiAbstract : Kromatografiska metoder kan användas för en mängd olika tillämpningar, inklusive separation, rening och analys av biomolekyler och kemikalier. Membrankromatografi är en av de nya kromatografiteknikerna som expanderar snabbt eftersom den tillåter hög masstransport genom den stationära fasen, vilket resulterar i en mer tidseffektiv process.
