Laser-Induced Breakdown Spectroscopy (LIBS)
Laser-Induced Breakdown Spectroscopy uses pulsed laser as an excitation energy carrier. Laser irradiance value of more than hundreds of GW per square cm evaporates and ionizes small amount of target material.

Interfacial rheology
With interfacial rheology the viscoelastic behavior and stress relaxation of an interface can be characterized. If there are interfacially active components (surfactants, polymers, nanoparticles...) present, they make this more complex. These compounds adsorb and form a layer at the interface. When the available interfacial area changes, the interfacially active components react to the deflexion out of the equilibrium state.

Analysis of the transmission and backscattering behaviour
Time- and space-resolved measurement of transmission and backscattering are used for dispersion stability analysis.

Optical contact angle measurement
The optical analysis of drops that hang from a dosing needle or are placed on a solid surface facilitates the determination of different surface and interfacial parameters. The contact angle that a liquid drop establishes on a solid surface characterises the solid’s wetting behaviour with said liquid.

Surface energy analysis for the verification of treatment effects on different polymer substrates
The effect of polymer treatments on four polymer substrates was tested by surface energy analysis using an optical contact angle measuring and contour analysis system of the OCA series from DataPhysics Instruments.

One-click surface energy determination with pressure-based double dosing system DDS-P for the OCA series
The pressure-based double dosing system DDS-P in combination with the optical contact angle measuring and contour analysis system OCA and its corresponding software from DataPhysics Instruments, enables the determination of the surface energy of a solid with one click.

Contact angle measurement of lipstick using optical contact angle measuring and contour analysis system OCA 25
The wetting behaviour of molten lipstick mixtures was tested using the DataPhysics optical contact angle measuring and contour analysis system OCA 25 in combination with a Peltier temperature control unit TPC 160 and an electrical needle heating device NHD 400.

Studying the tempering process of chocolate to understand the effect of the cooling rate on its quality
The MultiScan MS 20 from DataPhysics Instruments is a compact and versatile measuring device for optical stability and aging analyses. It provides the possibility to study tempering processes of chocolate easily and conveniently.

Stability analysis of whey based beverages using DataPhysics MS 20
Using the DataPhysics MS 20 stability analysis system and its corresponding MSC software, an easy and fast way to study the stability of whey beverage formulations is demonstrated.

Stability analysis of seasoning oil mixtures with DataPhysics MS 20
With the MultiScan 20 (MS 20) dispersion stability analysis system form DataPhysics Instruments stability changes can be detected and evalauted in a quantitative way much faster than any traditional shelflife test would permit.
