This case study describes how Ludof Pharmaceutical Ltd supported a global provider within animal health with its analytical requirements for an antibiotic used in animals - in order to free up laboratory capacity within its own facility. The customer was looking for a partner to sub-contract some straight forward routine analyses. Effective collaboration between the customer and Ludof Pharmaceutical Ltd made it possible to rapidly eliminate a problem that could have jeopardised the whole project. This project illustrates that access to analytical method development expertise can be invaluable.
