Test material
Reference
- Name:
- Unnamed
- Type:
- Constituent
- Details on test material:
- - Name of test material (as cited in study report): Corsair Clear #34
- Substance type: Clear white lumpy solid
- Physical state: Solid
- Stability under test conditions: Stable
- Storage condition of test material: At room temperature in the dark
- Radiolabelling:
- no
Study design
- Test temperature:
- 35°C
HPLC method
- Details on study design: HPLC method:
- According to the guidelines, the determination of the Koc for test substances that are ionized for at least 10% within pH 5.5 to 7.5 should be performed with both the ionized and non-ionized form. Therefore, the pKa values of the test substance were calculated using the Perrin calculation method (pKalc 5.0, module in Pallas 3.0, CompuDrug International San Francisco, CA, USA). Based on the calculations, the HPLC analysis was performed at neutral pH.
Analytical conditions:
Instrument: Alliance Separation Module 2695 (Waters, Milford, MA, USA)
Detector: Photodiode Array Detector 2996 (Waters)
Column: Hypersil BDS-CN, 150 mm x 4.6 mm i.d., dp = 5 µm (Thermo, San Jose, CA, USA)
Column temperature: 35°C +/- 1.0°C
Mobile phase: A - 55/45 (v/v) methanol/water B - Methanol
Since it proved not possible to elute the test substance with the recommended mobile phase composition of 55/45 (v/v) methanol/water under isocratic conditions, a gradient (to 100% methanol) was applied in order to elute the test substance and rinse the column.

Flow: 1 ml/min
Injection volume: 10 µl
UV detection: 210 nm
Test solution:
From earlier experiments it was known that the test substance could not be dissolved in mobile phases containing > 25 volume % of water. Therefore, a 1774 mg/l test solution of the test substance was prepared in methanol. In order to dissolve the test substance completely the stock solution was ultrasonicated for 5 minutes.
Results and discussion
Adsorption coefficient
- Type:
- log Koc
- Value:
- > 4.5
Results: HPLC method
- Details on results (HPLC method):
- In the chromatogram of the test substance solution, six test substance peaks were observed. The peaks between 0.9 and 3.6 minutes and at 27.6 minutes were also observed in the chromatogram of the blank solution. Therefore, it was assumed that these compounds did not derive from the test substance.
