Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC))
- Deviations:
- yes
- Principles of method if other than guideline:
- Testing was carried out in the totally unionised form at pH 3.5, however, it was not possible to carry out testing in the fully ionised form as this would have required testing at pH>13 which would have been detrimental to the stationary phase of a cyanopropyl column. Therefore testing was carried out at pH 7 as this would simulate typical neutral environmental conditions. Testing showed that there was no significant change in results with pH, only minor analytical variation.
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- UK GLP standards (Schedule 1, Good laboratory Practice regulations 1999 (SI 1999/3106))
- Type of method:
- HPLC estimation method

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
