Advantages of core-shell particle columns in Sequential Injection Chromatography for determination of phenolic acids
Original language description
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 {= 610 PSI, their conditions matched those of a commercially produced and optimised SIC system. The selectivity of each of the tested columns, Ascentis (R) Express RP-Amide, Ascentis (R) Express Phenyl-Hexyl and Ascentis (R) Express C18 (30 mm x 4.6 mm, core-shell particle size 2.7 mu m), was compared by their ability to separate seven phenolic acids that are secondary metabolite substances widely distributed in plants. The separations of all of the components were performed by isocratic elution using binary mobile phases composed of acetonitrile and 0.065% phosphoric acid at pH 2.4 (a specific ratio was used for each column) at a flow-rate of 0.60 mL/min. The volume of the mobile phase was 3
