dc.descriptionA comparative study of retention in different systems of flow control that provide linear dependence with the temperature of the column's head pressure is performed by numerical simulation considering multistep (or multiramp) PTGC (programmed-temperature gas chromatography) as the most general situation. Calculation algorithms for each flow control mode are developed on the basis of a general retention equation and the only additional hypothesis is that certain geometric parameters of the column remain practically constant along the program. Procedures are individually contrasted with experiment, prior to application. The comparative view indicates that simple correlations cannot be obtained between retention times and temperatures in two different pressure controls or pressure programs. It seems that numerical procedures are unavoidable when it is required to convert the retention data from one chromatographic system to another with the same stationary phase.
