GPC
The TSKgel column series also includes four columns for
the analysis of polymers at ultra-high temperatures (up to
220 °C). The TSKgel HT2 columns are specifically designed
for the analysis of organic-soluble polymers at extremely
elevated temperatures. The attributes of the TSKgel HT2
column series are listed in Table 3.
