Testing Included:

The system was powered on and successfully connected to QSoft Pro control software. Communication was established with the QCM-D electronics and automated liquid-handling system. All eight sensor positions displayed green status indicators.

An automated flow-mode program was configured as two consecutive four-sensor measurements. Measurement 1 was assigned to sensors 1-4, while Measurement 2 was assigned to sensors 5-8.

Measurement 1 & 2 were operated at 20.0°C and a programmed flow rate of 20 µL/min. The system was primed with Milli-Q water and then exposed to 1× PBS, followed by another Milli-Q water rinse and a 10% v/v ethanol solution. Real-time frequency and dissipation data were recorded across multiple harmonics.

Temperature control was also tested. The system was set to 14°C and allowed to reach the programmed temperature. After reaching 14°C, the temperature was set to 70°C and the system was allowed to heat.

Testing was limited to the functions described above. The system was not calibrated, and measurement accuracy was not independently verified.

Condition notes:

Pump #4 has a cracked/chipped syringe body but still pumps as it should (see photo #10) and the pogo pins for sensor #8 have been fully replaced (see photo #9, they are shorter but still connect to the chips without issue). Please see the photos of the acquired data. Sensors 5, 7, & 8 produced unexpected results, likely due to abnormal liquid deposition where sample fluids were not appropriately supplied to the sensor at the correct time.

About this system:

"The Biolin Scientific Q-Sense Omega Auto is a fully automated Quartz Crystal Microbalance with Dissipation Monitoring (QCM-D) platform designed for real-time, label-free analysis of molecular interactions, adsorption, mass changes, and viscoelastic properties at surfaces and interfaces. The system uses quartz crystal resonator sensors to simultaneously monitor changes in resonance frequency and energy dissipation, enabling characterization of thin films, biomolecular layers, polymers, proteins, surfactants, lipid membranes, coatings, nanoparticles, and other surface-bound materials. The Omega Auto provides an 8-sensor platform capable of automated sample handling, programmable sample changes and mixing, with eight sensors available for stagnant-mode measurements or a 2 x 4 sensor configuration for independent flow experiments. Its automated fluidics are particularly useful for high-throughput, multistep, and long-duration QCM-D experiments while reducing manual sample handling and improving experimental reproducibility. Q-Sense QCM-D technology is widely used in surface science, materials research, biomaterials, biophysics, biotechnology, pharmaceutical development, biosensor research, adsorption studies, interfacial chemistry, and nanotechnology for sensitive monitoring of nanoscale mass and structural changes."

Shipping:

Due to the size and weight of this system, it must be shipped via freight. Buyer is responsible for the cost of freight shipping to their facility.
