1. Study Summary The chemical structure of Sample Report was characterised. Spectroscopic analysis included FT-IR spectroscopy, UV-vis spectroscopy and qualitative 1H and 13C NMR spectroscopy.
HPLC-UV analysis confirmed the purity of the sample. Further analysis by HPLC-MS (TOF) determined the identity of the impurities detected by HPLC-UV. Additional analysis included thermogravimetric analysis to determine the inorganic content and water content determination by oven coulometry.

3.2 UV-Vis Spectroscopy
Sample Preparation:
An approximate 1000 ppm sample stock solution was prepared by adding 10 mg of sample to 10 ml volumetric flasks, dissolving in text removed for sample report by sonicating for 30 mins, allowing to cool and then making up to volume text removed for sample report buffer solution.
100 µl of the 1000 ppm stock solution was pipetted into a 10 ml volumetric flask and made to volume with text removed for sample report buffer resulting in a 10 ppm sample solution. The resulting solution was then transferred to a quartz UV cuvette and analysed with baseline correction via the UV/Vis method above with text removed for sample report buffer solution as the blank.

an additional 50 ml of appropriate solvent followed by sonication for a further 20 minutes. The solutions were then quantitatively transferred to 100 ml volumetric flasks and made to volume with the appropriate solvent, yielding approximate 2000 ppm solutions. The resulting solutions were transferred to HPLC vials and analysed via the above method with water and acetonitrile as the blanks.

3.6 Ashing for inorganics Sample Preparation:
Approximately 250 mg of sample was accurately weighed into a pre-dried, weighed porcelain crucible and the total mass recorded.
The sample was then placed in a muffle furnace and heated to 750oC and held at that temperature for 2 hrs.
The sample was then allowed to cool and reweighed.
