For instance, this is how my company calculates standard compliance which must pass the spec before either of the working standards can be used to quantify samples:
Typically prepare 2 working standards (A and B). To ensure compliance, the most common calculation is:
(Difference in weight adjusted areas/Mean of weight adjusted weights)*100
Spec is typically NMT 2.0% difference. If spec passes, then either A or B Standard can be used to quantify samples like assay, swabs, blends etc.
Do any users use this calculation? Its used all over our company!
