SCA 21 Analysis of the wetting properties of printing ink
SCA 21 â?? surface free energy
 Analysis of the surface free energy of solids, as well as the contributing components (e.g. dispersive, polar and hydrogen bond parts, acid and base portions, respectively) according to nine different theories. Representation of wetting envelopes and work of adhesion/contact angle diagrams.
SCA 22 â?? pendant drop
 Analysis of surface and interfacial tension, as well as the polar and dispersive contributions, based on the analysis of the drop shape.
SCA 23 â?? lamella contour
 Analysis of surface and interfacial tension based on the evaluation of the lamella contour.
SCA 24 â?? drop on fibre
 Analysis of the static contact angle according to the generalized length-width-method for the drop-on-fibre or wetted fibre setup and the dynamic contact angle according to the lamella-ring-method.
SCA 26 â?? oscillating/relaxing drop
 Analysis of the real and imaginary part of the interfacial dilatational modulus based on the oscillating or relaxing contour of pendant drops.
Software to maximise the return on your investment
The SCA software assists you in the intuitive use of all OCA instruments â?? whether making single CA/IFT measurements with the budget-priced OCA 15EC through to the fully automated contact angle and drop shape contour analysis instrument for microstructures, the OCA 40 Micro. If your application dictates that you choose a 'dynamic' solution; whether using a standard videoÂ­ system with 52 images/s sample rate or the ultra high-speed video system with 2200 images/s sample rate the SCA software will guide you through the steps required to maximise the impact of this invaluable 'movie' footage and the analysed data sets generated. DataPhysics has specialised in the development of highly precise and reliable methods for evaluating drop contours in combination with statistical error analysis. At every step of hardware and software development the quality of the data produced by its combination has been a crucial consideration.

The SCA software is designed as a modular program. Under Windows 7Â® / VistaÂ® it works in 32- and in 64-bit mode; under Windows XPÂ® only in 32-bit mode. The available software modules are:
SCA 20 â?? contact angle.
SCA 21 Â­â?? surface free energy.
SCA 22 â?? pendant drop.
SCA 23 â?? lamella contour.
SCA 24 â?? drop on fibre.
SCA 26 â?? oscillation / relaxation.
