You seem to be of the opinion that one may never use 'in house'
This is not true. One may choose to use published 'standard methods' as
you put it, but one is always free to use other methods provided that
there is supportive validation.
You mention the USP specifically - The above concept holds true for both
general information chapters in the USP (>1000) and official compendial
chapters in the USP (<1000), provided that you can show your method(s)
to be equivalent or better than the published method.
If you would like to discuss in more detail the implications of using
non-compendial methods we can, but I won't get into it in this e-mail.
To everyone in the group -
I'm glad to be back in the loop. And Laura did find me.
