Range : 2.70

Standard Deviation : 6.91

Validation:
The linearity of the detector response with respect to concentration was assessed over the nominal concentration range of 10 to 50 mg/L. The results were satisfactory with a correlation coefficient (r) of 1.000 being obtained.
Assessment of the sample recovery procedure was performed and proved adequate for the test; at a nominal concentration of 0.15 mg/L, a mean percentage recovery of 101.2% was obtained (range 99.8 to 102.4%).
Test sample concentrations have not been corrected for the recovery of analysis.
Discussion:
On completion of the equilibration period, the samples were clear with excess test item present at the bottom of the test vessels. The solutions were decanted, avoiding excess test item prior to centrifugation. After centrifugation, the supernatant was taken for analysis. The supernatant was visually observed to be clear and free from un-dissolved test item.
The preliminary water solubility test indicated that the column elution method should have been performed as the solubility was less than 1x10-2g/L. However, due to the large sample volume required for analysis, the column elution method was impractical. Therefore the flask method was used.
The test item consisted of several components therefore the impact of loading rate was assessed. A loading rate increase of 10 times produced approximately 3 times the analyzed result. It was therefore concluded that the higher loading rate was sufficient to saturate the more water soluble components. The results showed that the test item was not fully saturated after 24 hours shaking therefore the result reported is the mean of the higher loading rate, shaken for 48 and 72 hours.
The earlier eluting peaks of the test item had significantly higher water solubility than the later eluting components resulting in significant differences in the peak profile between
samples and standards. As the exact quantities of each component in the standards were unknown the results were calculated on the basis of total peak area.
