Theoretical and practical aspects of flow control in programmed-temperature gas chromatography


Behavior pattems for the temperature dependence of cohann head pressure and outlet volumetric flow rote are analyzed for some particular configurations of chromatograph's flow control system. Cuantitative prediction of this behavior, and specially it’s effect on gas hold up time, is evaluated the attention is centered on the application to PTGC retention simulation.
