Determination of the Amount of Borneol in Some Chinese Patent Medicine by GC on a Sol-Gel Capillary Column

Sol-gel capillary column is a new type of chromatographic column that has a relatively simple technological process for the developing of the column. Good separation is achieved on this column. It stands high temperatures and shows excellent stability and repeatability. In this research a sol-gel capillary column is developed with hydroxy-termi-nated poly(dimethylsiloxane) as stationary phase and borneol in some Chinese patent medicine is analyzed on the column. The results show good precision and accuracy. The standard deviation is 0. 0369 and the relative standard deviation is 1. 13% . The average recovery is 96. 2% .
