Sensor probes for O2, pH and CO2
Monitoring analyte distributions inside packages - non-invasively without having to destroy the container - bears many advantages. VisiSens™ can be applied to test packaging materials for their permeation properties and leak tightness. Furthermore, special transport conditions inside the containers can be monitored and verified. In a very special research project, concerning the transport of immobilized plant cells, VisiSens™ oxygen, pH and CO2
imaging was applied to determine the activity of the cells in hermetically sealed transport vessels over several days. It is difficult to predict the time at which depletion of nutrients (sucrose, O2
) or accumulation of end products (CO2
) limits survival of cells under these conditions.
