Query1

% stability calculation:

❝ one by calculating the % accuracy. i.e 85-115% of nominal conc.

❝ Percent Stability


[%]Stability = 100 x Mean Conc. of Stability Samples /
Mean Conc. of Comparison Samples

Query 2:

Precision and Accuracy:


❝ For the determination of the stability, fresh CC and QC samples are

❝ prepared, in such case is it necessary to prove the precision and accuracy

❝ of the freshly prepared QC samples. i mean to say whether it is necessary a

❝ to analysis the P& A batch along with the stability samples.


No need to prepare freshly prepared QC samples along with fresh CC. Compare the stability QC samples with first day P&A batch QC samples.
