Abstract : This technical report describes an experimental study of the reliability of a glass capillary gas chromatographic system to assign tentative peak identity according to relative retention times under carefully controlled operating conditions. The first phase of the effort involved the set-up, calibration, and optimization of the capillary system. Optimization was realized with the maximum resolution between selected pairs of hydrocarbons in a minimum of sample analysis time. Peak resolution was investigated as a function of carrier capillary pressure and temperature programming rate. A reference hydrocarbon was chosen. The repeatability of relative retention times was determined for: normal alkanes, branched alkanes, olefins, alkyl benzenes, alkylated napthalenes, saturated cyclic alkanes, and alkyl anilines that could be present in JP-4.
