High-temperature liquid chromatography HTLC

During the last few years, other methods for PO microstructure analysis have been proposed. Of these, the high-temperature liquid chromatography (HTLC) is the most promising. Using two sets of columns, one may fractionate the polymer according to composition (TREF part) and then MW (SEC part) or vice versa. [Pg.1580]

Fortunately, as the complexity of macromolecules increases, the precision and sophistication of instruments designed for their characterization improve. The analytical and preparative fractionating columns of GPC used in the 1950s are transformed into automatic multicolumn, multi-detector, high-temperature SEC. Similar advance is observed for TREF and CRYSTAF, now fused into CFC. At the same time, new methods are being developed for faster and more precise characterization by means of the multi-detector liquid chromatography, HTLC or HPLC. [Pg.1582]
