These combination electrodes, employing the use of solid gel, were designed with the water industry very mush in mind. Capable of being used with portable instruments, and on-line, they will give optimum performance in cold water. The gel retains salt, and maintains zero potential for a much longer period of time. The mechanical strength of the gel allows the use of a junction with a much higher porosity than previous designs. This benefits the user in the following ways:

 

1. The response time to equilibrium is improved, especially at low temperatures. (high porosity = low temperatures)

 

2. Accuracy is improved due to liquid junction potentials, or “errors” in samples of different ionic strength being minimised.
