 We currently operate 4 GPC systems which consist of the following:
A Standard GPC with DRI and UV-VIS detector
An absolute molecular weight system incorporating triple detection (DRI, LALLS and VISCOMETRY)
A high molecular weight system (up to 13 million a.m.u) with a DRI detector
A standard DRI system with changeable eluents, for example DMF or aqueous phase.
A Standard GPC with DRI and UV-VIS detector
SEC Analyses are performed on a modular system comprising the following units: an LC-10ATVP Shimadzu solvent delivery system, a SIL-10ADVP Shimadzu auto-injector with a stepwise injection control motor with an accuracy of ±1µL, a column set which consisted of a PL 5.0µm bead size guard column and a set of 3 ´ 5.0µm PL linear columns (103, 104, 105 Å) kept at at constant 40ºC inside a CTO-10AC VP Shimadzu Column Oven and an RID-10A Shimadzu Refractive Index Detector. Tetrahydrofuran THF) was utilised as the continuous phase
