A closer look

Let's dive into the specifications of QSense Pro. You can also compare the data to other QSense instruments to find what you are looking for.

Compare QSense range

Measurement range and capacity

Measurement channels
Working temperature 4 to 70 °C, 4 to 150 °C using accessory chamber (QSense High Temperature chamber)
Sensors (frequency range) 5 MHz (1-72)
Number of measured harmonics 7, allows for full viscoelastic modeling


Sample and fluidics 

Minimum sample volume, stagnant mode ~ 20 μl
~ 1 μl minimum dispense volume
Minimum sample volume, flow mode ~ 50 μl
Flow rates Typical flow rate 20 µl/min. Flow speed range 1-40 µl/min (4 sensors), 1-100 µl/min (1 sensor).

Performance characteristics 

Maximum time resolution 100 data points per second (each data point represents an f and D value)
   LOD (3 x noise)    1.08 ng/cm2
Sensitivity/limit of detection and noise See the graph below
   Minimum noise

   Frequency: 0.02 Hz

   Mass: 0.4 ng/cm2

   Dissipation: 5∙10-9

Long-term stability* Frequency: < 1 Hz/h
Dissipation: < 0.15∙10-6
Temperature: < 0.02˚C/h

* 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 below figure and table describe the real-measurement performance of QSense Pro for each acquisition mode using all channels. The sample interval can be significantly shortened (~4 times) by using a single channel.

Pro LOD graf

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 15 µL/min. Each measurement mode was measured for approximately 5 minutes.

What our customers say

Our instruments are present at many prestigious universities and research facilities worldwide. Take a minute to find out what others say about QSense. 

Prof. Nam-Joon Cho, School of Materials Science and Engineering, Nanyang Technological University, Singapore

"QCM-D technology is a key part of our biointerfacial science research that spans fundamental biomacromolecular investigations to applied studies involving antiviral drug development. The QSense instruments, which we have used for nearly two decades, are robust and can track complex biological phenomena in real-time and with label-free readouts that have helped us to deeply characterize a wide range of systems related to proteins and lipid membranes. Together with our analytical modeling efforts, there is a really bright future to continue applying QCM-D technology in new directions across many important scientific disciplines."

Nanyang_Technological_University-Logo.wine

Nanyang Technological University, Singapore

Nanyang Technological University (NTU) is ranked one of the 15 top universities worldwide by QS World University Rankings. This research-intensive public university has over 33 000 undergraduate and postgraduate students and is home to world-class autonomous institutes.

Joshua A. Jackman, Assistant Professor, Sungkyunkwan University, South Korea

"Using QSense measurement tools, our lab has investigated many very interesting protein and lipid systems in aqueous and non-aqueous environments and the QCM-D measurement capabilities have proven critical to study molecular-level interaction behaviors at solid-liquid interfaces. One of the most exciting examples has involved antimicrobial lipids, in which case the QCM-D technique has proven extremely useful to distinguish the mechanisms of action of different compounds interacting with membrane-mimicking supported lipid bilayers. Such mechanistic distinctions were seen for the first time by the QCM-D technique, demonstrating its potential to complement and in some cases surpass the analytical capabilities of traditional biological assays. Looking forward, we see enormous potential to translate fundamental insights obtained from QCM-D measurements into numerous applications across the healthcare, biotechnology, and agricultural spaces among various opportunities."

Sungkyunkwan-University

Sungkyunkwan University, Korea

Founded already in 1398, Sungkyunkwan University has a rich history of producing high-end research scientists. Today, it is ranked number one among the private universities in Korea. Sungkyunkwan University takes great pride in its innovative spirit and puts resources into research and development.

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

"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. 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."

Implementing quartz crystal microbalance with dissipation monitoring for the development of novel biosensing assays

Exosomes have shown great importance in intercellular communication and disease transmission. As result, there has been a significant increase in trying novel biosensing platforms that can detect exosomal content such as proteins and nucleic acid with a view toward application in diagnostic assays. This webinar by Prof. Guldinwill present recent efforts on implementing quartz crystal microbalance with dissipation monitoring (QCM-D) for reliable biosensing.
