You may also connect the plastic tubing to the Pt-tube before the assembly is mounted onto
the main block (see step 10b).
11. Test again if the quartz crystal is mounted properly as shown in step 8. If it is not, you must remove
and readjust the quartz crystal.
12. Start any optional temperature-control system and optional flow system. Run your experiment.
Connection of Working (Green) and Working Sense (Blue) Leads to eQCM 15M
The eQCM 15M has two 2 mm banana connectors on the front side to connect a potentiostat to the quartz
crystal. This allows you to perform EQCM experiments where the quartz crystal additionally serves as working
electrode.
Plug the green working electrode lead of the potentiostat's cell cable into the W.E. jack (see Figure 5-2).
Connect the blue working sense lead of your potentiostat's cell cable to the W.S. jack.
A binding post on the rear panel of the eQCM 15M is provided for grounding purposes. A water pipe can be a
suitable source of earth ground, or an AC mains ground is also suitable.
