Our nanoparticle experts cover physical and chemical analysis expertise, and can provide comprehensive R&D or analysis capabilities in compliance with good manufacturing practices for particle or suspension nanosystems.

    Carbon Nanotube Analysis and Characterisation

    The quality of carbon nanotubes varies with production conditions, so carbon nanotube manufacturers need reliable data on structure and quality to optimize production and verify their products. Similarly, downstream users also need to ensure the quality of carbon nanotubes used in products. Alfa Chemistry scientists have professional chemical analysis technology and many years of analytical research experience, and can help customers analyze and characterize carbon nanotubes.

    Analysis of Nanoparticles in Pharmaceuticals

    Nanoparticles have been developed for a range of medical product applications, including drug delivery, controlled release systems, and medical devices. The analysis of drug nanoparticles can provide a wealth of information to help product development, especially for complex drug delivery technologies, formulations, or product characterization. Therefore, experienced analysts need to operate complex analytical techniques to provide reliable data and insights to support drug development activities.
