LOSS On Drying:
Method:TGA
Results
0.0120%
Chromatographic purity(GC):98.90068%
Loss On Drying:0.012%
Assay(100% method):98.9%
Uncertainty:±2.0%
The calculation of the 100% method follows the formula:
Assay(%)=(100%-Loss On Drying)*Purity GC(%)/100%
Loss On Drying is considered as absolute effect, GC 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.
