Applications

Life Science

From measurements in liquids to solid samples or soft tissues in life science varied samples are analyzed on a regular basis. With their convenient handling and versatile analytical capabilities the flexible WITec imaging systems provide the opportunity to adjust the imaging technique to changing requirements and are particularly well-suited for life science.

Pharmaceutics, cosmetics

The development and production of drug delivery systems requires efficient and reliable control mechanisms to ensure the quality of the final products. These products can vary widely in composition and application. Therefore analytical tools such as the WITec imaging systems that provide both comprehensive chemical characterization and the flexibility to adjust the method to the investigated specimen are preferred in pharmaceutical research.

Materials science

Materials science is a diverse field including the development and testing of new substances, as well as the refinement of manufacturing processes and quality control for existing products. WITec imaging systems are particularly well-suited for comprehensive sample analyses in materials science and provide the opportunity to acquire a thorough knowledge of the sample surface morphology and chemical composition.

Geoscience

WITec confocal Raman imaging systems are excellent analytical tools for the comprehensive investigation of geological samples, such as the identification and characterization of minerals, or in the observation of mineral phase transitions in high and ultra-high pressure/temperature experiments.

Polymers

WITec imaging systems enable comprehensive sample analysis that provides a thorough characterization of the physical and chemical properties of the polymers on the nanometer scale.

Nano-Carbon & 2D Materials

2D materials such as carbon nano-tubes, graphene or transition metal dichalcogenides (TMDs) show immense promise in many applications such as transistors, sensors, and optoelectronics. Flexible and adaptive analytical methods can support effective investigation and accelerate progress in 2D materials research and development. For comprehensive investigations of nano-carbon and TMD samples WITec microscopes can be equipped with various imaging techniques such as confocal Raman imaging, AFM, and SNOM, all fully integrable in a single microscope.
