✦ Synopsis

A procedure is described and evaluated that allows the calculation of linear temperature-programmed retention indices from accurate Kovats retention indices on a given stationary phase and their temperature variation coefficients. The influence of experimental factors such as column film thickness, phase ratio and variation of Kovats retention indices, column dead time and carrier gas flow-rates are examined. The calculation accuracies are 10.5 retention index units in most instances. The applicability and limitations of the procedure are discussed.
