SAMPLE PREPARATIONS
- 20.17 mg of the test item were dissolved in 50 ml of acetonitrile, and then diluted with water I acetonitrile =1 : 1.
- For calibration, small amounts (7.1 - 82.1 mg) of reference compounds were dissolved in 20 ml of acetonitrile under ultrasonic
treatment, and then the flask was filled up to volume (100 ml) with water. These solutions were injected into the HPLCsystem.
