Latest Patents

One of his latest patents is a reference liquid designed for calibration or quality control of instruments that determine ionized calcium and pH levels. This reference liquid contains a specific calcium ion activity and a pH-buffer, making it suitable for calibrating both calcium-sensitive and pH electrodes. The pH-buffer is a nitrogen-containing organic sulfonic acid, with a pK in the range of 6.6-7.6. The ionic strength of the reference liquid is maintained between 0.15-0.17, with a buffer capacity in the range of 0.04-0.10, and it is conveniently packed in glass ampoules.

Another significant patent involves an electrochemical measuring electrode device for polarographically measuring the partial pressure of oxygen in an electrolytic medium. This device features a cathode capable of reducing oxygen and an anode that communicates electrolytically with the cathode through the medium. A membrane covers the exposed cathode surface and defines an electrolyte chamber. To enhance the response time of the electrode, a stable, non-biological catalytic means, preferably constituted by platinum black particles, is integrated into the design.
