Chromatographie en phase gazeuse réalisée simultanément avec une programmation de température et une programmation du gradient longitudinal négatif de température : Théorie de la rétention et influence des paramètres

Abstract

Gas chromatography using simultaneously programmed temperature and a programmed longitudinal negative temperature gradient. Retention theory and influence of parameters A new method for gas chromatography is described using a linear programmed temperature associated with a linear programmed longitudinal negative temperature gradient. As the gradient is negative, the temperatures at the column inlet are higher than those at the column outlet. The description of the apparatus is followed by an elaboration of the theory of retention of solutes. The role of various parameters is specified: column length, column temperature at the time of injection, rate of growth of temperature at column inlet and column outlet.
