Dear, good afternoon
I am writing from chile
That I can modify an analytical methodology and remains pharmacopoeia?
In specific modifications made they included:
- Increased HPLC injection volume (of 50uL to 80uL)
- Change 30cms to 15cms column (same type)
- Flow 2ml / min at 0.8ml / min
Applies perform a complete validation ??? or just a verification of the methodology???
there is a guide in which I can support ???
thank you very much
Greetings!!!

People have at times claimed both options. Look carefully at the relevant pharmacopia: does it explicitly state that those changes are allowed? The last ione, 2 ml/min to 0.8 mL/min seems to far to allow a simple verification, and requires validation. But another expert may have some support verification.
