Polyalkenes, other synthetic polymers, and water-soluble macromolecules have been investigated using Highspeed GPC systems. Highspeed GPC can be a big time-saver in two-dimensional chromatography applications, which require about 10 h of analysis time for cross-fractionation. This can be reduced by a factor of ten to about 1 h, which makes it much more appealing for many laboratories. Details of these and additional Highspeed applications can be found in Refs. [3b, 4].
