Solution of high concentration of
inertsalt, preferably comprising cations and anions of equal
mobility, optionally interposed between the
reference electrode filling and both the test and
standard solution, when the test solution and filling solution are chemically incompatible. This procedure
introduces into the operational cell a second
liquid junction formed usually in a similar way to the first. (This definition refers to a
bridge solution of a double junction
reference electrode.)
