PROGRAMMED-TEMPERATURE RETENTION INDEXES - A SURVEY OF CALCULATION METHODS

Retention temperatures of various solutes were measured on an OV-105 column under different heating rates. The experimental results agree with those evaluated by means of the equation of Curvers et al. Several methods of assigning programmed temperature retention indices to each solute were tested. Comparison of the results does not allow a clear choice of any of the methods, although a procedure based on an interpolation through the use of cubic splines polynomials is preferred. The sensitivity of the various procedures towards small changes in the input data is reported. © 1990.
