Hello!

I´ve been trying to analize Lymecycline API with the monograph suplied by the European Pharmacopoeia, wich suggest using Tetracycline Reference Standard.
The movile phase is rather tricky, and I´m still trying to adjust the proportions and to figure out wich of the two peaks I get belongs to Tetracycline.
Anyway, I´d like to know if anyone around here is using the same monograph and could help me with this.

Thanks a lot,

Daiana.
