*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. The specifications above are valid for this configuration. All specifications are subject to change without notice.

Add more possibilities

QSense High Pressure is based on our most versatile QCM-D instrument QSense Explorer. If you want to perform measurements in ambient pressure, you can always expand your possibilities with our Explorer chamber. We have selected a few add-ons you might be interested in.

Electrochemistry Module

For simultaneous QCM-D and electrochemistry measurements on the same surface. Enables cyclic voltammetry and electrochemical impedance measurements to explore polymer behavior, electrostatic interactions, corrosion etc.

Ellipsometry Module

Enables simultaneous QCM-D and ellipsometry measurements on the same surface, which allows for quantification of solvent content in the film. It also gives a refined analysis of the morphological changes of the adsorbed film.

Window Module

The Window Module allows optical access to the sensor surface through a sapphire window. It enables experiments with UV-induced reactions and when used in the QSense Explorer chamber, the compact design also enables microscopy studies of reactions on the sensor.

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 High Pressure.

Prof. Dennis R. Heldman, The Ohio State University

"Our laboratory uses the QSense High Pressure QCM-D system for the study of the reactions occurring at the interface between a surface and a high-protein liquid food. Information about the rate of fouling on the surface and the composition of the foulant has provided new and important insights before scale-up to pilot and commercial-scale experiments with a focus on the contributions of flow characteristics over the surface. These new and different insights provide our laboratory and others with a completely new and different dimension to our research.”

The Ohio State University

Ohio State University, OSU, is the highest-ranked public university in Ohio and home to the Department of Food Science and Technology. The work of Prof. Dennis R. Heldman centers around food engineering, with emphasis on process design to achieve maximum efficiency and optimum food product quality.
