Applications of TSKgel H-TYPE Gel PERMEAtion columns
SOLVENTS AND FLOW RATES
TSKgel H series columns can be applied to analyse the molecular mass
distribution of a broad variety of organic-soluble polymers. Table 5 lists
the recommended solvents by application for TSKgel H series columns.
Super H columns are ideally suited to save analysis time and solvent
by semi-micro GPC. For optimum performance they should be used in
combination with a low dead volume GPC instrument such as the all-in-
one EcoSEC system. Table 6 suggests optimum flow rates to be applied
for TSKgel SuperH and TSKgel H
