S16-03662 test item-Bulk material	TOC [%] 53.0

 

Test item concentration calculation:

C(test item in sample) in mg/L

TOC(sample) in mg/L

TOC(test item) in %

 

C(test item in sample) = [TOC(sample) / TOC(test item)] *100% = [173 mg/L / 53.0%] * 100% = 326 mg/L

 

Results display the required reproducibility (relative standard deviation is < 15%, deviation between the means of Flask 1 and Flask 2 is < 15%).

The water solubility of the test item was determined to be 326 mg/L in ultra-pure water at a temperature of 20 ± 0.5 °C at a pH 4.44.
