A sol-gel method was used in preparing capillary gas chromatographic columns with simplicity and rapidity. Due to the formation of the chemical bonds between the coating layer and the inner wall of the capillary, the thermal stability of the column was greatly increased. The sol-gel poly(dimethyl-siloxane) (PDMS) column was able to withstand temperatures as high as 400 degrees C. This column showed excellent separation of free fatty acids, amines, and other polar compounds. The sol-gel column… CONTINUE READING
