Porometry, gas-liquid expulsion method
Standard capillary flow porometry is useful to characterize the pore structure of materials such as membranes, filter media, ceramics, paper, textile and similar materials. A non-toxic liquid is let spontaneously fill the pores in the sample and a non-reacting gas displaces the liquid from pores by increasing the gas pressure.

Bidirectional oscillating streaming potential method
DataPhysics patented a measuring technique that uses an oscillatory flow of electrolyte solution through or along the sample. The streaming potential and the currently applied pressure are measured simultaneously together with the temperature, conductivity and pH value of the electrolyte solution. Through the wide range of applicable flow frequencies and amplitudes a fast and precise measurement is possible.

Electrophoretic Light Scattering (ELS)
Electrophoretic light scattering (ELS) is a technology for measuring electrophoretic mobility via Doppler shifts of the scattered light. When an incident light illuminates dispersed particles that are subjected to an applied electric field, the frequency of the particles’ scattered light will be different from the incident light due to the Doppler effect. The frequency shift is measured and converted to provide the electrophoretic mobility.

Studying the stability and kinetics of fast-breaking foam using face cleansing foam with the MultiScan MS 20
The DataPhysics MultiScan MS 20 stability analysis system and its MSC-software provide a fast and simple way to study the stability and kinetics of quick-breaking foam. Changes can be detected sensitively and objectively.

Stability analysis of temperature-sensitive cutting fluids using the MultiScan MS 20
The DataPhysics MultiScan MS 20 stability analysis system provides a simple and reliable method to observe temperature-dependent changes in cutting fluid emulsions and analyze its thermal stability. Notably, the technique has internal heating device and respective temperature controllers, so that it can be used to develop and optimize the product at specific temperatures.

Stability study of a commercial protein shake using the DataPhysics MultiScan 20 stability analysis system
The stability of a liquid protein shake sample was tested using the MultiScan 20 stability analysis system. By analysing the transmission and backscattering behaviour of the dispersion, unstable components were detected and various destabilisation mechanisms could be distinguished within a very short period of time.

Stability study of a pesticide formulation using the DataPhysics MultiScan 20 stability analysis system
The stability of a liquid pesticide formulation sample was tested using the MultiScan 20 stability analysis system. By analysing the time-dependent transmission and backscattering behaviour of the dispersion, unstable components were detected and various destabilisation mechanisms could be distinguished within a short period of time.

Stability study of battery coating slurries using the dispersion stability analysis system MultiScan MS 20
Analysing the time-dependent and position-dependent transmission and backscattering intensity of different slurries, unstable slurry formulations could be identified within a short period of time which is valuable information in the development and optimisation of battery slurries.

Measuring contact angles on leaves at different relative humidity using DataPhysics HGC
The influence of relative air humidity on the wettability of plant leaf surfaces can be studied with a combination of our humidity generator HGC and optical contact angle measuring device OCA. The following note uses Miscanthus leaves as an example to present this technique.
