What is the 3T Analytik qCell series?

This series comprises the the best entry-level Quartz Crystal Microbalance with Damping/Dissapation(QCM-D) instruments available. The products offer unmatched stability, patented easy to handle sensors, and are budget friendly.

What is qCell?

The qCell is the entry level sensor platform for the full range of QCM-D experiments. In comparison to the full-fledged sensor system qCell T, qCell has no Peltier system for thermal control and no automatic pump control. The software qGraph manages sensor data collecting and processing. Alterations in mass adsorptions, layer thickness and sample viscosity are obtained with high accuracy, controlled against blank, in a time resolved manner.

What are the features of qCell?

• Single Sensor Channel
• Dissipation/Damping & Frequency Monitoring
• Smart System
• Optional Fully Automated Pump Operation
• User-Friendly Software Interface
• Plug-and-Play USB Connection

What is qCell -T?

The qCell T are highly advanced quartz crystal microbalance instruments with damping/dissipation monitoring for gaining real time insights into molecular interactions, biofilms, liquid properties,, and even the analysis of blood.The QCM-D device qCell T offers unmatched stability, unique operational ease and accuracy, in real-time measurements.

What are the features of qCell-T?

• Single or multiple QCM Sensor Channels (depending upon the instrument)
• Dissipation/Damping & Frequency Monitoring
• Peltier Driven Temperature Control
• Fully Automated Pump Operation
• User-Friendly Software Interface
• Plug-and-Play USB Connection
• Easy Controls

What is qCell T eChem?

The qCell T eChem is the electrochemical version of the QCM-D  qCell T instrument. The sensor platform is specifically adapted to combine the full range of electrochemical experiments with the specific insight of quartz crystal microbalance sensors. A potentiostat or galvanostat from Metrohm can be operated independently through its Nova control software, while qGraph qCell T software acquires sensor data, thermo control, and fluidic data.

Special features of the qCell T eChem include a simple connection to  a potentiostat, along with all the other features of the qCell T instruments.

How does the Flow Cell work?

With only 30 µl internal volume, the flow cell is designed for easy access, fast sensor replacement, and to maintain a good seal in its closed working condition. All surfaces in contact with liquid samples are made of highly chemical -esistant materials, e.g., Teflon.

The flow cell head (top) is positioned over the sensor placed in the cell socket and locked with a quarter turn in a bayonet style. A tight seal is maintained by a thin O-ring which rests on the sheet – and not on the sensor – virtually eliminating any tension and ensuring high signal integrity.

After priming, the quartz sensor is exposed to the liquid and the measurement can begin.

The flow cell head can be equipped with a fully transparent plug, allowing the user to visually follow the experiment over its time course.

What is the Optional Fluidic Control?

The qCell series offers also optional fluid control with high accuracy and repeatability. The flow rate can be precisely adjusted from 9 µl/min to 5600 µl/min.

The minimum flow rate reaches down to 9 µl/min and the 12 roller peristaltic pump provides high accuracy and repeatability, even under low flow rate. Along with the minimum sample volume requirement of 80 µl, the fluid system makes the qCell series the optimal instrument for laboratory and industrial applications using high cost fluid samples.

What software are the instruments equipped with?

The qCell series comes with a complete software suite (qGraph) for instrument control, signal acquisition, real time display, processing and data storage. The software is preinstalled and delivered with an All-in-one PC.

Individual panels display frequency, damping (dissipation), temperature, and pump flow profiles. Online protocol commenting, coordinate display by pick point function, scripts for programming flow rates, patterns, and repetitive cycles, can be added and edited by the user. Data export to qGraph Viewer, Excel, Origin, and other processing software is supported.
