✦ Synopsis

Abstract

A Chromolith Performance octadecylsilyl (ODS) monolithic silica column (Merck) was compared with a conventional microparticulate ODS‐bonded silica column in the high‐performance liquid chromatography separation of natural polyprenols. A system comprising two connected monolithic columns afforded an equivalent separation at half the analysis time of the conventional method. Furthermore, ten connected columns achieved a tremendously high‐resolution separation, in which the complicated series of homologous polyprenols with geometric isomerism were fully separated.

## Abstract In this work, the simultaneous analysis of five triazolopyrimidine sulfoanilide herbicides (flumetsulam, florasulam, metosulam, cloransulam‐methyl, and diclosulam) by HPLC using UV detection and a C~18~ monolithic column is proposed. The mobile phase which was composed of ACN, water, an
