eSorption Probe from 3T Analytik – Surface Analysis | IGZ Instruments
In materials science, polymer research and pharmaceuticals, understanding how surfaces interact with gases, vapors or moisture is of central importance. The eSorption Probe from 3t analytik uses proven QCM (Quartz Crystal Microbalance) technology to visualize these processes in real time.
This method can be used to precisely monitor adsorption, absorption and desorption processes. This is essential for:
-
The swelling behavior of polymers: Precise analysis of how materials react and swell on contact with solvent vapors or moisture.
-
The characterization of coatings: Testing the stability, density and permeability of thin films and coatings.
-
Moisture absorption in pharmacy: Analysis of the hygroscopicity of active ingredients and excipients to optimize formulations and storage conditions.
Compatibility: The eSorption Probe can be combined with other analytical methods—for example, for multimodal characterization using Raman spectroscopy or electrochemistry (EQCM-D)
Benefits at a Glance
- No water system required – minimal maintenance
- Direct immersion or pipetting instead of complex fluidics
- Compatible with the qCell and qCell T sensor platforms from 3T Analytik
- Real-time, label-free measurement
The eSorption probe
This video shows the eSorption Probe from 3T Analytik in action: The slim sensor-probe holder can be integrated directly into multimodal measurement setups—combined with electrochemical methods (EQCM-D) and Raman spectroscopy. This enables in-situ measurements that reveal surface reactions and changes from multiple perspectives simultaneously, without the need for complex fluidics or elaborate experimental setups.
