Test Solution
A 1500 mg/L stock solution of the test item was prepared in methanol. The stock solution was diluted with 54.4/45.6 (v/v) methanol/water. The final concentration of the test item solution was 0.200 mg/L.
The test item blank solution was 55/45 (v/v) methanol/water.
Sample Injections
Reference substance and test item solutions were injected in duplicate. Blank solutions were analyzed by single injection. - Key result
