* The temperature stability depends on variations in how the ambient affects the warming or cooling of the chamber. The specified temperature stability may not be reached if the room temperature changes more than ± 1° C, if there is a draft or a heat source nearby. ** Data has been collected for standard QSense flow module (data from single frequency mode, one data point is collected every 5 seconds, the Sauerbrey relation is assumed to be valid). The stated sensitivity for the QSense High Pressure system states a worst case scenario for how much the liquid on the back side of the sensor can reduce the sensitivity. *** Data has been collected for standard QSense flow module (data from multiple frequency mode [all harmonics], 4 data points are collected within 1 second, the Sauerbrey relation is assumed to be valid). The stated sensitivity for the QSense High Pressure system states a worst case scenario for how much the liquid on the back side of the sensor can reduce the sensitivity. **** Depends on the resonant frequency of the sensor, and the density and the viscoelastic properties of the deposited film. Values given here are only approximate and applicable for a 5 MHz sensor with a polystyrene adlayer. The specifications above are valid for this configuration. All specifications are subject to change without notice.

Malkiat Johal on QSense

"I have found QSense to be one of the best techniques for an undergraduate lab because it’s turnkey and it requires very little maintenance."

Johal Malkiat-1

Malkiat Johal, Professor of Chemistry, Pomona College

"The operating principles are straightforward and the students can focus on the science. And so, that’s something that we have been really happy with, it really works in this kind of setting. It’s an ideal method for an undergraduate surface science lab."

citat8

Jodie Lutkenhaus on QSense

"We can monitor the mass change of our system in real-time. I can tell you that for every electron moved, this amount of mass changed. That’s powerful. You can’t really get that with any other system."

Jodie Lutkenhaus

Jodie Lutkenhaus, Associate Professor, Texas A&M University

"We use the QSense high temperature model that allows us to investigate polyelectrolyte complexes and their response to temperature. We’re also using the electrochemistry module so we can run our standard electrochemical measurements at the same time as we run the QCM-D."

citat8

Kenichi Sakai on QSense

"We regard QCM-D as a valuable measuring tool due to its high sensitivity and stability and find it applicable for versatile studies because of its availabilities of sensors with various different types of surfaces. In this context I would say QCM-D is the best suitable solution for simulating a variety of nanoscale interaction behaviors both real-time & in-situ.

Jodie Lutkenhaus-1

Kenichi Sakai, Associate Professor, Tokyo University of Science

"We are working on academic research in the field of colloid and interface chemistry and our main work is synthesis of novel surfactants and characterization of their properties. We use QCM-D as a must-tool to comprehend molecular adsorption/desorption behaviors specifically observed at a solid-liquid interface."

Marité Cárdena on QSense

"QSense instruments are a great tool for our biophysical research. They enable rapid screening for biomolecular interaction at lipid bilayers and also allow optimising the parameters for deposition of thin films."
