Example Setup for Self-Assembled Monolayers Studies
- Injection Port in Center of photo
- Sulfur containing molecules injected into the port and allowed to flow over the gold electrode surface of the crystal.
- The frequency shift (Hz) and Resistance (ohms) are measured as a funciton of time to determine the rate of adsorption onto a gold surface
- The manual, with detailed operation instructions, can be found here:
