CORRELATION STUDY USING SATURATED HYDROCARBONS AS A MODEL, OF THE RETENTION TIME IN GLC AND DIFFERENT PHYSICO-CHEMICAL PARAMETERS
Using a model of 27 saturated hydrocarbons, the logarithm retention times relative to n-hexane were correlated with 11 physico-chemical properties. For all correlations studied, where log t rr was used as a dependent variable, the correlation based on log t rr vs. critical pressure presented statist...

| Sumario: | Using a model of 27 saturated hydrocarbons, the logarithm retention times relative to n-hexane were correlated with 11 physico-chemical properties. For all correlations studied, where log t rr was used as a dependent variable, the correlation based on log t rr vs. critical pressure presented statistical parameters indicating that this relationship is the optimal one within the set being studied. The multi-variable regression studies gave significantly smaller Fisher indices than that obtained in the previously indicated relationship. Principal Component Analysis (PCA) applied to all treated variables indicated that only one linear combination exists with a statistically significant value accounting for almost all of the data variability |
