Pulse Residence in Short Chromatographic Columns

• Description:
  By a simple geometric construction the mean residence time in linear chromatography is shown to be independent of the degree with which equilibrium Is attained. The general relationship is that if a constant input of m mol/s leads to a steady-state accumulation of M moles in the column, the mean residence time for a pulse input is M/m s. This leads to simple calculations of the effects of input and effluent boundary conditions on the mean residence time. Although an irreversible chemical reaction reduces the residence time, a procedure is available to determine the residence time in the absence of chemical reaction. The residence times following inputs into the mobile and stationary phases, respectively, differ by a constant. [Description provided by NIOSH]
