Abstract

The chromatographic behavior of some hydrocarbons and some of their nitro derivates after preconditioning with solvent vapors has been investigated. After preloading with cyclohexane or hexane an improved separation of some sample pairs is observed. Furthermore, inversion of R~f~ values takes place. The preloading of the reversed‐phase plates permits utilization of mobile phase with higher water content, thus leading to a significant shortening of developing time.

## Abstract The results of investigations with ion pair chromatography on RP~2~, RP~8~ and RP~18~ thin layers are described. Heptane sulphonic acid is used as ion pair former. The best results are achieved on RP~18~‐layers with the counter ion in the mobile phase.
