Numerous technologically important polymers, for example, many crystalline polyolefins are soluble only at the elevated temperature. Consequently, the high-temperature SEC instruments were designed, in which also dissolution and filtration of samples is performed at elevated temperature. Some SEC eluents such as hexafluoro isopropanol are very expensive, other ones are very aggressive—the extremes represent concentrated sulfuric acid [150] or hexamethyl phosphorotriamide [151] used as the mobile phase for some polyamides or cresols for polyesters [152]. Many biopolymers solicit the appropriate environment (eluent) and/or temperature of experiment below the ambient value to prevent their denaturation. Some polymers rapidly degrade in solution, for example, poly(hydroxy butyrate). These are to be separated as rapidly as possible and the data obtained should be corrected.
