Characterization of stationary phases in gas chromatography using linear solvation energy relationships
(Northern Illinois University, 1994)
Linear solvation energy relationship (LSER) was used for characterization three stationary phases with cyano- function group : sebaconitrile, benzyl cyanide and tetracyanoethylated pentaerythritol(TCEPE). We examined the ...
Characterization of fluorine-containing stationary phases by linear solvation energy relationships
(Northern Illinois University, 2000)
Linear solvation energy relationships (LSER) have been used successfully in the characterization of GC stationary phases and other materials. The LSER model has also been used to quantify solubility properties of the solute ...
LSER characterization of amine functional stationary phases
(Northern Illinois University, 1996)
The linear solvation energy relationship is one of the various methods used to characterize gas chromatographic stationary phases. An analysis of retention data yields a quantitative relationship between the solute and ...
Membrane-gas chromatographic system for counter-current extraction and determination of phenols in aqueous samples
(Northern Illinois University, 1993)
A system combining counter-current membrane extraction and gas chromatographic analysis was evaluated and tested using phenol and 2,4-dichlorophenol as a test sample mixture. The phenols were successfully extracted from ...
Investigation of the retention mechanism for brush type bonded phases in gas and liquid chromatography
(Northern Illinois University, 1975)
The mechanism of retention for chemically bonded stationary phases of the SiOR type, where -R is an organic molecule with a polar functional group, has been investigated. Sample size studies in conjunction with thermodynamic ...
