Results
Number ofresults:n=3Average:0.5606%
Chromatographic purity(HPLC): 100.0000% 
Water Content: 0.5606% 
Assay(100%method): 99.4% 
Uncertainty: ±2.0% 
The calculation of the 100% method follows the formula:
Assay(%)=(100%-Water Content)*PurityHPLC(%)/100%
Water Content is considered as absolute effectHPLC purity is considered as relative effect.
The uncertainty values are the expanded uncertainty and represent an estimated standard deviation equal to the positive square root of the total variation of the uncertainty of components.Anormal distribution is assumed and a coverage factor of K=2 is chosen using approximately a 95% confidence level
