Catheter electrode for electrochemical analysis

摘要

The electrical sensor of the present invention for electrochemical analysis comprises a sheath and at one end thereof a semi-permeable membrane which is impermeable for macromolecular materials and bacteria, and further is comprising a measuring probe insertible to said sheath. The sheath is constructed in the form of a pericatheter and the measuring probe comprises a completely self-contained sensor, capable of operating independently of the said sheath, the membrane of said sensor being in direct contact with the membrane of said pericatheter.
