Hi Helmut,

❝ Logic behind: When you weighed the standard in, it was within its shelf life and therefore, the concentration of the stock solution correct. The drug in the stock solution doesn’t “care” that the standard expired.

Thank you for this logic explanation. I think as a regulatory person you must have a very vast academic scientific background in different fields beside to check every morning this forum otherwise you will lose.

Have a nice day,
Osama
