The quartz crystal microbalance (QCM) technique under electrochemical frequency is very useful to determine many compounds such as metal proteins, metal ions and thiol-conjugated oligonucleotides.
The Resonance frequency of quartz changes when material attaches to the electrode’s surface. This product is capable of super-micro quantitative analysis by using this unique behavior.

Thickness of 10 MHz quartz is 0.16 mm. Accelerating the oscillation frequency means to make the quartz thinner and delicate. Resolution and easiness to care for should be taken into the consideration. We can offer two surface conditions of quartz – Polished and Unpolished. Polished one has a 100 Å thickness of gold layer on a titanium adhesive layer. We would recommend the unpolished quartz if there is a possibility that the titanium layer might effect on your experiment. We would like you to note that the gold layer on the unpolished quartz peels off easier than the polished one because it does not have adhesive layer.

This cell even can be used in two ways, with the choose of PEEK Cell or Acrylic Flow Cell.
- Acrylic Flow Cell, for QCM Flow Mode
- PEEK Cell, for EQCM Mode
