A new column format known as parallel segmented flow has recently been introduced, whereby improvements in column performance are observed. These improvements are achieved via the separation of eluent from the column core from that of the column wall region. The segmentation of flow is accomplished immediately as the eluent exits the column through the use of a multi-channel end fitting. The ratio of flow exiting through the column central port relative to the peripheral ports, known as the segmentation ratio, can be tuned to optimise chromatographic performance. Investigations into the use of parallel segmented flow chromatography columns have demonstrated increased sensitivity and theoretical plates in analytical scale isocratic separations, but so far no studies have detailed the performance of these columns in gradient elution. The current study addresses the performance of parallel segmented flow columns in gradient elution, detailing the reproducibility of the gradient at various segmentation ratios and compares the performance to conventional columns. The study found that there was no observable difference in the gradient shape, or reproducibility of the gradient profiles generated at any segmentation ratio, tested on three different types of stationary phases. A separation of an 11-component test mixture verified that the primary advantage of parallel segmented flow columns was that the peak volume was reduced in proportion to the segmentation ratio.
