Abstract

Dead volume cannot be avoided in measurements of kinetic and transport parameters using pulse gas chromatography. A criterion is derived for the bed volume necessary to make these dead volume effects negligible. Application of the criterion and assumptions made in its development are discussed.

Abstract

One ne peut pas éviter l'existence d'un volume mort dans les mesures cinétiques ou de paramètre de transfert par chromatographic en phase gazeuse par impulsions. On a établi pour le volume du lit un critère nécessaire pour rendre ces effets négligeables; on discute l'application de ce critère ainsi que les hypothèses faites.
