Abstract

An on‐line system for coupling a normal phase liquid chromatography (LC) column to a reversed‐phase LC column is described. The interface consists of an on‐line solvent evaporator working on the principles of concurrent eluent evaporation and vapor overflow, and two additional 10 port valves. Optimization of the on‐line procedure as well as recoveries, repeatability and linearity characteristics were tested in a simplified system simulating determination of heavy polycyclic aromatic hydrocarbons in edible oils. An application on a real extra virgin olive oil sample is also reported. © 2001 John Wiley & Sons, Inc. J Micro Sep 13: 13–18, 2001
