Hexafluoro-2-propanol (HFIP) has proven to be a useful gel permeation chromatography (GPC) solvent for a number of polymers which have hydrogen bonding sites. Its UV transmission, refractive index, viscosity and solubility properties permit its use with a variety of GPC detectors and columns. Exa...
2.4.1 Solvent Selection 溶剂选择 The most important criteria in preparing todo a GPC analysis is finding a suitable solvent to dissolve the polymer. This soundstrivial enough, but remember that GPC is a separation technique based on thesize of the polymer in solution. Polymer chains will open...
