Pre-cleaning of sensor A new sensor might be contaminated with hydrocarbons and dust. Pre-cleaning the surface will give more reproducible QCM-D results.
Protocol For light cleaning, step 2 – 4 below can be used.

  1. Sonicate the sensor surfaces in 99% ethanol for 15 minutes.
  2. Rinse with milliQ water.
  3. Dry with nitrogen gas.
  4. UV/ozone treat for 10 minutes (see UVO treatment).
Usage QSensors are intended for one-time use only.
Storage Store in a cool, dry place out of light.
Shelf life Stable at least 12 months from package date in unopened package, see expiry date on package.
Chemical compatibility Do not expose to strong acids and bases. Stay within pH 4-9 to avoid corrosion. There is no guarantee that the coating will be stable under all experimental conditions.
