A short hose with a T piece can be found in the accessories of the measuring cell. The
hose and the T piece are applied to the adapter and connected to the exhaust hose. One
side of the T piece remains open. The acetic acid vapors can be drawn out of the detec-
tion module effectively without the electrolyte solution evaporating too rapidly.

A pair of generator electrodes generate the silver ions needed for chemical precipitation.
The pair of electrodes consist of a platinum cathode with a salt bridge and a silver an-
ode.
