Short summary

A microfluidic-cartridge-based measurement technology utilizing miniaturized solid-contact liquid-membrane ion-selective electrodes with direct potentiometry for application in hydroponics is presented. The system provides fully automated nutrient analysis and dosing, minimizes sample volume, reduces waste, and is an ideal setup for on-site deployment. Measurements within hydroponic greenhouses show excellent correlation with the expected values for the target ion concentrations.
