QCM-I Setup for Measuring the Effect of Humidity on Thin Films

The QCM-I and QCM-I Mini systems are designed to be modular so that they can be configured to use the sensors and sample environments that are most appropriate for the user’s experiments. This technical note summarizes the basic configurations that can be used with the QCM-I for measuring the effect of changes in humidity on […]

Synchronizing QCM-I (QCM-D) Measurements Using the Digital IO Port

The BioSense 3 software controls and records experiments using the Quartz Crystal Microbalance with Impedance (QCM-I) instrument. Other instrumentation can also be controlled with the software to provide integrated experiments, e.g. Gamry potentiostats for electrochemical QCM-I measurements. Other equipment can also be synchronized with the QCM-I experiment using the digital In/Out port. This technical note […]

Fluidic Configurations for QCM-I / QCM-D

Pump Flow Control with Manual Sample Introduction It is recommended that samples are introduced to the QCM-I flow-cells using a pump to control the flow. In the simplest setup, shown in figure 1, a peristaltic pump* is used to suck buffer directly from a beaker or other container. Sample is introduced to the flow-cell by […]
