System, method, and probe for monitoring pH levels of a sample medium
First Claim
1. A method of forming a pH-sensitive electrode, the method comprising:
- drawing a molten solution comprising some amount of antimony into a disposable tube;
cooling the molten solution to form an antimony rod;
detaching a fragment of the antimony rod after removing the antimony rod from the disposable tube;
forming a sensing portion of the pH-sensitive electrode by dipping one end of the fragment into the molten solution and allowing the sensing portion to harden while the pH-sensitive electrode is secured in a downward-pointing direction, wherein said forming creates a sensing portion having a substantially smooth hemispherical configuration adapted to maximize a stability of the pH-sensitive electrode.

Abstract
A system for monitoring a pH level of a sample medium is disclosed herein as including a pH probe having a pH-sensitive electrode, a reference electrode and a temperature electrode arranged within a housing of the pH probe. The probe housing generally includes a flexible inner tube and a flexible outer tube, the inner tube being concentrically arranged within the outer tube. Preferably, a size of the probe housing minimizes the amount of trauma introduced by insertion of the pH probe into physiological tissues, muscles or fluids. The system also includes a processing means, which is coupled to the pH probe for determining the pH of the sample medium. A method of forming a pH-sensitive electrode, a method of manufacturing a pH probe, and a method for using a pH probe are also disclosed herein.
