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.
We use a variety of complementary technologies to verify the key structure and quality parameters of carbon nanotubes. Information from each technology helps to construct a comprehensive map of the structure and quality of nanotube samples.

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.
