4.Final Result
Loss On Drying:
Method:TGA
Results
0.0707%
Chromatographic purity(HPLC):99.9339%
Loss On Drying:0.0707%
Assay(100 % method);99.9%
Uncertainty:±2.0%
The calculation of the 100% method follows the formula:
Assay (%)= (100%-Loss On Drying)* Purity HPLC(%)/100%
Loss On Drying is considered as absolute effect, HPLC purity is considered as relative effect.
The uncertainty values are the expanded uncertainty and represent an estimated standard deviation equal to the positivesquare root of the total variation of the uncertainty of components. A normal distrbution is assumed and a coverage factor ofK=2 is chosen using approximately a 95% confidence level.
