Bivariate Distribution

Polymer Char's CFC


The CFC can analyse molecular weight distribution through fractionation of the samples with a TREF separation process which continuously injects resulting fractions towards the online GPC columns for a second fractionation. Therefore, it is able to complete the cross-fractionation without any loss of information.
