Oligosaccharides

Oligosaccharides are thermally unstable and have to be derivatized into the well-known oxime-trimethyl-silyl derivatives. The limits of HTCGC are illustrated in Figure 9. An oligosaccharide sample, obtained by hydrolysis of insulin extracted from Cichorium in-tybus, with DPs ranging from DP1 to DP12 could be analysed in approximately 30 min on a 10 mx 0.53 mm i.d. x 0.1 | m methylsilicone column. The degree of polymerization (DP) is the number of sugar units in the oligosaccharides. Both the pressure (50200 kPa) and the temperature (100-430°C) were programmed to elute the high DP numbers. The analysis was performed on an aluminium-clad column. In this application resolution is sacrificed for speed of elution.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
