Measurement principle of KRUSS DSA100 series droplet shape analyzer:
The optical droplet shape analysis method is adopted: the contours of seat droplets, suspended droplets and captured bubbles are captured by high-definition cameras, and the contact Angle, surface tension and interfacial tension are calculated by using mathematical models such as Young-Laplace, conic sections, circle fitting and the high-width method. And the surface energy of the solid and its polarity/dispersion/acid-base/hydrogen bond components are calculated through multi-liquid tests.
Measurement methods and options of KRUSS DSA100 series droplet shape analyzer:
Measure the contact Angle between the liquid and the solid
■ All common models can be used to calculate the surface free energy of a solid based on the contact Angle
■ Static contact Angle, advance Angle and retreat Angle
The contact Angle of fibers was measured by the meniscus method
Roll Angle measurement was carried out on hydrophobic and superhydrophobic surfaces
■ The surface tension and liquid-liquid interfacial tension were measured by the suspension drop method
Achieve constant temperature measurement within the range of -30 to 400 °C
Measure at the preset humidity
■ Rheological analysis of surface and interface (elasticity, viscosity)
■ Tilt Angle measurement
Tasks and applications of KRUSS DSA100 series droplet Shape analyzer:
■ Evaluate the process of surface treatment
Research on Adhesion and Stability of Bonding Coating Process
■ Study the coating materials in accordance with DIN55660
■ Wettability test of plastics, glass, ceramics, wood, paper, fabrics or metals
■ Surface cleanliness test
Automatic positioning enables comprehensive sample analysis
The DSA100 series is equipped with a software-controlled three-axis automatic sample stage, which can quickly and accurately move the sample to the preset measurement position. This enables it to conduct a complete and standardized analysis, which is highly ideal for quality control. In addition, wetting analysis can be conducted based on the position of the sample to check uniformity or evaluate the differences between coated and uncoated areas, for example, the differences between coated and uncoated areas.
Sturdy shell design and time-saving setup
The sturdy housing of the DSA100 series can protect sensitive components (such as cameras) and minimize the impact of vibration to the greatest extent.
Usually, when measuring the contact Angle, the viewing Angle needs to be adjusted. However, due to the existence of a special optical device, the position of the droplets in the image does not change during this step, allowing for no need to readjust the sample
The height of one's character can change the perspective of observation. Compared with the traditional optical path design, it can better measure larger samples.
