Apr 6, 2019 · In QCM-I, the impedance of the quartz crystal sensor is measured using a network analyzer to accurately determine the frequency and bandwidth of the crystal resonance. This is done over multiple frequency ranges to measure the fundamental and overtone resonances.

Shop for QCM sensor crystals with a variety of coating and metalization options and quartz crystal microbalance devices and accessories.

The QCM-I (QCM-D) measuring unit is a high-sensitivity mass sensor, which measures the change in frequency of a quartz crystal resonator and as a label free biosensor it measures the “wet mass” of the adsorbed layer in processes occurring at or near the sensor surface.

The QCM-I Mini (QCM-D) measuring unit is a high-sensitivity mass sensor, which measures the change in frequency of a quartz crystal resonator and as a label free biosensor it measures the "wet mass" of the adsorbed layer in processes occurring at or near the sensor surface.

We offer Quartz Crystal Microbalance (QCM) devices with impedance measurement and dissipation monitoring (QCM-D), including a combined QCM-I OWLS Net system, and many smaller configurations like the QCM-I, the QCM Mini.
