DISPOSABLE SYSTEM FOR ION SELECTIVE ELECTRODES FOR LONG TERM MONITORING

摘要

Disposable system for ion selective electrodes for long term monitoring. An ion sensitive system has sets of microfluidic microchannels forming ion sensitive electrodes by the assembly of a substrate (6) with structured microchannels and another substrate (7) comprising metal contacts (8) on its surface. The integrated ion sensitive sensors are each composed of a microfluidic microchannel (1) to contain an electrolyte, another microfluidic microchannel (2) to contain the analyte and another microfluidic microchannel (3) to contain a membrane liquid that separates the electrolyte from the analyte at the confluent junction of the three solutions. The system has the dimension of a thin and small disc and can be incorporated in an analyzing device.
