This type of information might help us to write an SOP (I know no one will want to "donate" their own SOP for this). Thanks.
Off-topic conversations and chit-chat.

Can't you use the history of stability to argue that daily calibration checks are not required ? This kind of QA can become an infinite regress - how do you know that the balance is stable ?, how do you know that the certified mass is stable ?, how do you know that the fundamental constants really are constant ?!
This smacks of QA people not having enough to do to keep themselves busy.

That's been discussed, but our UV-visible spectrophotometer is not cGMP-qualified, that would cost thousands of dollars a year. Our cGMP assays are by GC, HPLC, and a few titrations.
