title: Enhanced separation performance using a new column technology: parallel segmented outlet flow.
abstract: A new column technology - termed parallel segmented outlet flow was employed here to illustrate gains in separation performance that are achievable by the active management of flow as it exits from the outlet of the chromatography column. Parallel segmented outlet flow requires a column be fitted with an outlet fitting that separates flow from the central region of the column from that of wall region. Each region of flow is able to be processed independently, such that post column detection emulates end column localised detection. As a result of this flow segmentation and the subsequent more efficient means of detection, column efficiency was observed to increase by more than 20%, with gains in sensitivity by as much as 22%, and a decrease in peak volume by up to 85%.
