4.Final Result
Loss on Drying:
Method: TGA
Results
0.38%
Chromatographic purity(HPLC):99.5%
oss on Drying:0.38%
Assay(100% method):99.1%
Uncertainty:±2.0%
The calculation of the 100% method follows the formula:
Assay (%) = (100%-Loss on Drying) * Purity HPLC (%) /100%
Lcss on Drying is considered as absolute effect, HPLC purity is considered as relative effect.
The uncertainty values are the expanded uncerainty and represent an estimated standard deviation equal to the positive square root of the total variation of the uncertainty of components. A normal distribution is assumed and a coverage factor of K=2 is chosen using approximately a 95% confidence level.
