Calculation of water solubility

Sample description	A	B	F
Standard solution 46.8 µg/L	1847
Test solution - a	n.d.	<18.7
Test solution - b	n.d.	<18.7	<18.7

 

A: Peak area

- A(standard): Standard solution

- A(sample): Sample

B: Concentration of test item (µg/L)

- B = C * A(sample) / A(standard) * D / E

C: Concentration of test item in standard solution (46.8 µg/L)

D: Final volume (2 mL)

E: Sampling volume (1 mL)

F: Average concentration of test item (µg/L)

 

The values were regarded as less than the limit of quantification (18.7 µg/L) because the test item was not detected from the test solution.

 

The pH measured for test solutions a and b were 6.1 and 6.0, respectively.
