| Abstract: | Determination of the
contents of normal paraffins and carbon number distribution in liquid paraffin wax and its
feedstock by means of capillary gas chromatography was reported in this paper. Liquid
paraffin wax and its feedstock were studied by using on-column injection, high temperature
quartz capillary column coated with aluminum and the method of programmed temperature.
This method has the advantage of simplicity, convenience, accuracy in quantitative analysis,
high precision. |
