* Maximum time resolution applying one measurement channel.
** 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.
All specifications are subject to change without notice. 


Optimal real-life performance

Applying a higher sample rate inevitably leads to higher noise and thus a compromised limit of detection (LOD). What aspect to prioritize depends on the studied surface interaction process. High time resolution may not be critical if very slow changes are studied, and a high measurement sensitivity may not be important if large changes are to be measured. With the 5 Speed-to-Noise modes you can select the right setting to maximize real-life performance for your measurement.

The figure and table below describe the real-measurement performance of QSense Analyzer for each acquisition mode. This is much more interesting than maximum values in a specification to understand what to expect from your instrument in a real measurement situation.

Speed and limit detection2

Speed and limit of detection (LOD) per acquisition mode. Limit of detection is set to 1 S.D. of the baseline noise.


Performance characteristics. Measurements were performed with QSX 303 SiO2 sensors at 20°C temperature, and in deionized water at a flow of 15µL/min, using one measurement channel. Each measurement mode was measured for approximately 5 minutes. Note that using more than one channel will reduce the measurement time resolution.

Marité Cárdenas 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 optimizing the parameters for deposition of thin films."

malmö universitet

Professor Dr. Marité Cárdenas, Health and Society, Malmö University

"The instrument is easy to use, and has a long working life as long as you follow the maintenance instructions! The technical staff at Biolin Scientific are a pleasure to work with: They are nice and always give quick feedback and support."

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 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."

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

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."
