ABSTRACT:
In the analysis of polymers which are generally soluble only at elevated temperatures, at least the chromatographic columns in a high pressure liquid chromatography system for the analysis of such polymers are located in an oven maintained at a temperature suitable for maintaining the polymer in solution. Preferably, the detector used is also operable at such elevated temperatures. However, other apparatus such as pumps and injectors are operated at lower temperatures.
