QSensors QSX 303 Silicon Dioxide (thin)

QSensors are developed and produced to provide you with stable, reliable and reproducible data. Full performance is ensured through extensive quality controls and guaranteed for one-time use according to the recommendations.


Sensor Specifications
Typically ships within < 1 week
Part Number QSX 303
Top coating material Silicon dioxide (SiO2) (50 nm)
Surface roughness < 1 nm RMS
Maximum temperature 150 °C
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 1, 4 and 5 below can be used.

  1. UV/ozone treat for 10 minutes
  2. Prepare a solution of 2 % Sodium Dodecyl Sulfate in milliQ water
  3. Immerse the sensor surfaces in the solution for 30 minutes in room temperature
  4. Rinse with milliQ water. It is important that the surfaces are kept wet after SDS immersion until they are rinsed well with water
  5. Dry with nitrogen gas
  6. UV/ozone treat for 10 minutes
Usage QSensors are intended for one-time use only.
Storage Store in a cool, dry place out of light.
Shelf life Stable at least 18 months from package date in unopened package, see expiry date on package.
Chemical compatibility Do not expose to strong bases. There is no guarantee that the coating will be stable under all experimental conditions.
