Evaluation of new micro solid-phase extraction cartridges for on-column derivatisation reactions

Abstract

A novel on-column derivatisation technique using micro solid-phase extraction (μ-SPE) cartridges has been evaluated and applied to the derivatisation of short-chain fatty acids in olive oil. The results show that μ-SPE is a good candidate for on-column derivatisation, giving good results with only a few microlitres of sample.
