Advantages of core-shell particle columns in Sequential Injection Chromatography for determination of phenolic acids
2013
Abstract
This article presents the first use of three different stationary phases: three core-shell particle-packed reversed phase columns in flow systems. The aim of this work was to extend the chromatographic capabilities of the SIC system.
Despite the particle-packed columns reaching system pressures of 0.997) and a system precision of 10 mg L-1 with a RSD = 1.87 and time for one analysis <8.0 min). The results of these experiments confirmed the benefits of extending chromatographic selectivity using core-shell particle column technology in a SIC manifold.
