In this work, an online sampling of plants combined with an efficient capillary electrophoresis (CE)-based method was developed and applied to study the kinetics of changes in the xylem sap composition and to assess plant fitness under stress conditions comprehensively [1,2]. A laboratory-built CE device was developed to provide online sampling and CE analysis of various ionogenic species in the plant sap during plant stress response. The short CE analysis time allows for capturing time-dependent kinetic changes in the living plant during the stress response. The developed device successfully monitored chloride, nitrate, and sulfate ions in the plant xylem during the salt stress or stress caused by nitrate deficiency.
