Quartz Microbalance Crystals (QCM) FAQs

To get answers to the most frequently asked questions about our Quartz Microbalance Crystals (QCM), please select one of the links below:


What are Quartz Microbalance Crystals?

Quartz Microbalance Crystals are also referred to as QCM which is a piezoelectric quartz crystal that utilizes the Converse Piezoelectric Effect to determine mass changes as a result of frequency change of the crystal. Material is coated onto the crystal that attracts a certain other material. When this other material becomes attached, it lowers the crystal frequency, the amount being directly related to its mass. The mass change can be in the nanogram range.

The quartz crystal microbalance (QCM) is an extremely sensitive mass sensor, capable of measuring mass changes in the nanogram range. QCM's are piezoelectric devices fabricated of a thin plate of quartz, with gold electrodes affixed to each side of the plate.

How are QCM crystals ordered?

To order QCM crystals, ICM requires frequency, size, metalization, surface finish and mounting requirements.

top


What is the minimum order required?

The minimum order for QCM crystals is normally 4 crystals, but some metalizations may have a larger minimum.

top


How long does it take to receive an order for QCM crystals?

A typical QCM crystal order takes 2 to 4 weeks.

top


What are the most common frequencies for ICM's QCM crystals?

The most common frequencies for ICM’s QCM crystals are 5.000 MHz and 10.000 MHz, although we can produce any frequency between 1.000 and 30.000+ MHz.

  • Al (Aluminum)
  • Carbon (C)
  • Chromium (Cr)
  • Cobalt (Co)
  • Cu (Copper)
  • Ni (Nickel)
  • Mo (Molybdenum)
  • Ni (Nickel)
