    Notes: Summary The microcomputer-assisted retention prediction system in C18 reversed-phase HPLC is described. The system is based on the use of the hydrophobic parameter and the correlation factor of alkylbenzenes and polycyclic aromatic hydrocarbons (PAHs) which are highly correlated to their retention in reversed-phase HPLC. The system is evaluated by comparing the retention data between measured and predicted values. One of the typical examples applied for PAH analysis in the extracts of diesel particulate matter shows the high potential of the system investigated.

    Correlations between van der Waals volume and retention data of alkylbenzene derivatives in reversed phase micro high performance liquid chromatography (1982)

    Notes: The structure-retention relationship in reversed phase micro high performance liquid chromatography has been investigated for substituted alkylbenzene derivatives. The correlation between van der Waals volume and retention data was completely linear and any deviation from this relation might becaused from the overlap volume of substituent alkyl chains. Standard enthalpies of transfer from the mobile to the stationary phase are also proportional to the van der Waals volume of each solute; the results indicate that the mechanism of reversed phase liquid chromatography might involve a solute-induced volume change in the mobile phase.
