How many vials from a CPC lot should I send for an HPLC purity test?

Asked 8 Nov 2025Modified 9 months agoViewed 3.7k times

What I have: CPC · an HPLC purity test.

I want the working, not the result — I need to be able to redo it with different numbers.

I care about the precision as well as the value — I want to know how many figures are real.

Where is my error, and what is the correct working?
