Abstract

Systems, methods, and cartridges taught herein improve chromatographic performance in electrospray systems that feature chromatographic columns having a conductive or semiconductive stationary phase by electrically connecting a fluid junction located upstream of the chromatographic column to a fluid union located downstream of the chromatographic column using an electrical conductor. The electrical conductor creates a voltage equipotential between a first end of the chromatographic column and a second end of the chromatographic column that neutralizes current flow through the chromatographic column. Accurate electrospray current measurements are enabled while post-column peak dispersion and repeatable retention time are achieved.
