This thesis is a total of four parts : 1 First, a brief description of the course of development of the gas chromatography , and elaborate on the kinetic theory of gas chromatography and thermodynamic theory based on the structure and construction of gas chromatography ; then largely used gas chromatography stationary phase , to be elaborated on the basis of new perspectives and traditional capillary GC column preparation . 2 , the second chapter of the sol - gel chemistry technology and application . The first principle of the sol - gel chemism forth then introduced the sol - gel technology applications in spectroscopy , electrical chromatography columns, solid phase micro extraction field of analytical chemistry , sol - Finally condensate the glue prepared capillary GC column , and many ways to explore the influencing factors of the sol - gel prepared by capillary GC column . Chapter 3 , the third is the use of sol - gel prepared by capillary GC column , modified polysiloxane , butyl acrylate , styrene , of styrene butyl acetate modified polysiloxane stationary phase PDMS graft macromolecules comparing both the separation performance of the coated capillary column stationary phase were used , thermal stability , column polarity and column efficiency . Will then replacement is vinyl trimethoxy silane monomers methyl trimethoxysilane system of the capillary column coated PDMS capillary column , the column having excellent separation performance , especially a good separation of amines , phenol and other organic substances , the column is anti-aging performance is very good , the service life is significantly longer . And then using the stationary phase of the small molecule glycerol prepared sol . Gel glycerol capillary GC columns, the use temperature of the column , the more traditional glycerin column greatly improved, significantly increased separation range can be separated from paraffins , alcohols, phenols, amines , and with benzene ring compound . 4 Chapter homemade sol - gel hydroxyl-terminated polydimethylsiloxane capillary column used in the actual separation . Determined by the internal standard method of ethanol in alcoholic beverages and adhesives harmful organic ingredients : homemade sol - gel column very short but complete separation of the various components analysis speed , short cycle accurate high.
