Electrochemical measurement cell
First Claim
1. An electrochemical measurement cell comprising an electrode holder containing a working electrode and a counter electrode, said electrode holder surrounded by an electrolyte space containing an electrolyte, having a leak rate no greater than one-half of the volume of the electrolyte space for a period of one to six months, wherein the electrolyte comes into contact with the electrodes, wherein the electrolytic space is partly delimited by a hydrophilic membrane.

Abstract
It is an of this invention to provide an electrochemical measurement cell capable of measuring the concentration of gaseous and charged or neutral compounds in a liquid. Accordingly, the present invention consists in one aspect in an electrochemical measurement cell having a working and a counter electrode surrounded by an electrolyte space filled with an electrolyte with a high viscosity, wherein the electrolyte space is at least partly delimited by a hydrophilic membrane. It has been surprisingly discovered by the present invention that charged or neutral compounds in a liquid, as well as gases, can be determined by means of an electrochemical measurement cell having a hydrophilic membrane and an electrolyte with a high viscosity.
