Abstract:
PCT No. PCT/GB92/01736 Sec. 371 Date May 18, 1994 Sec. 102(e) Date May 18, 1994 PCT Filed Sep. 21, 1992 PCT Pub. No. WO93/05701 PCT Pub. Date Apr. 1, 1993.A dialysis electrode device comprises a shank of needle-like proportions and formed from a hollow dialysis fiber membrane. The shank is closed at its distal end by a sealing plug and, at its proximal end, it is sealed to and in communication with an auxiliary chamber defined by a tubular body part. Electrolyte is supplied to the chamber in the shank through an inlet conduit and is removed via an outlet conduit connected to the auxiliary chamber. The device also includes a dialysis or first working electrode, which is insulated save for a length thereof disposed within the hollow shank, a counter electrode and a reference electrode mounted within the auxiliary chamber. It may be used in clinical medicine and the food, pharmaceutical and other industries where it is desirable to analyze or monitor the presence of chemical substances. In carrying out a microdialysis procedure in human tissue, for example, the device is primed with an enzyme electrolyte solution and electrical measurements are taken, in situ, of the concentration of a chemical substance diffusing into the shank chamber through the dialysis fiber shank.
