Ultra-performance polymer separations

Authors: Uliyanchenko, E.V.;

Ultra-performance polymer separations

Abstract

Vloeistofchromatografie (liquid chromatography, LC) is een analytische techniek waarmee het mogelijk is een monster te scheiden in verschillende componenten. Het scheidingsprincipe van LC is gebaseerd op niet-gelijke verdeling van moleculen over een stationaire en een mobiele fase. Onlangs is een nieuwe generatie LC-instrumenten (ultra-high pressure liquid chromatography, UHPLC) ontwikkeld waarbij het mogelijk is een hogere druk te genereren, wat het mogelijk maakt om LC-kolommen te gebruiken die bepakt zijn met zeer kleine deeltjes. Het gebruik van kleine deeltjes in LC geeft verbeterde scheidingsefficiëntie en/of snellere analyse. Hoewel UHPLC al succesvol wordt toegepast voor het scheiden van complexe monsters in bijvoorbeeld de farmacie, wordt het nog niet gebruikt voor de analyse van synthetische macromoleculen, zoals polymeren. Elena Uliyanchenko richtte zich op de mogelijkheden en beperkingen van UHPLC voor de analyse van verschillende polymeren. Ze laat de bruikbaarheid zien van UHPLC voor de scheiding van synthetische polymeren op basis van molecuulgewicht en chemische samenstelling. Ook toont ze de voordelen van tweedimensionale UHPLC voor de analyse van polymeren.
