文摘Tributyl citrate is used to make capillary column for GC by sol-gel as stationary phase.On the column the polarity,the thermal stability,and the separation power are studied.The results show that the sol-gel column has the higher thermal stability,better inertness,more efficient separations for alcohols,amines etc.,compared with the column made using conventional approach.
