Figure 5 Equipping the titration cell (coulometry)
Equip the titration cell as follows:
1
Place the 6.1903.030 stirring bar in the titration cell.
2
Cut the 6.2713.0x0 ground-joint sleeves to the correct length and
attach them to the ground joints of the inserts (electrodes, adsorber
tube, etc.).
Make sure that the edges of the ground-joint sleeves are cut to size
cleanly and that there are no fringes. The ground-joint sleeves must
not protrude at the lower edge of the ground-joint opening.
3
Insert the 6.1403.030 adsorber tube into the generator electrode.
