Correlation of Characteristic Thermal Constant and Elution Temperature in GC

In a temperature-programmed analysis, the solutes that elute at higher temperatures have generally larger characterisitic thermal constants, θchar. The change approximately matches the temperature-related increase in a carrier gas viscosity. Accounting for the effect allows reduction in the uncertai...
