Résumé

A continuous-flow method using a conductometric detector was developed to measure CO2 resulting from respiration of tomato fruit. The fruit are inserted into a 3.4-l vessel and the atmosphere in the vessel continuously monitored for CO2, using a closed-loop system. The CO2 produced from fruit respiration diffuses through a Teflon® membrane, dissociates in the acceptor stream of deionized water, and the conductivity (mainly of H+ and HCO3-) is monitored. The conductance increase in the acceptor stream is proportional to the carbon dioxide concentration in the gaseous sample.
