Chemical Analysis

The development of chemical analysis enables people to understand the relationship between chemical structure and function at different levels. For researchers, chemical analysis is also an indispensable test method in various industrial fields. In order to meet the needs of biosynthesis technology, chemical analysis lab of Alfa Chemistry is constantly improved. We select the most appropriate test items and develop the corresponding test programs according to the characteristics of the samples and your needs. If you are interested in our services, please feel free to contact us and talk to our experts.
