Results and discussion
Water solubility
- Key result
- Water solubility:
- < 0.02 mg/L
- Conc. based on:
- element
- Remarks:
- Fe
- Temp.:
- 19.8 °C
- pH:
- >= 6.1 - <= 6.2
- Remarks on result:
- other: by the column elution method
- Details on results:
- The concentration analysed in the samples from the blank column were comparable with the concentrations found in the samples from the loaded column at both flow rates. The analyzed concentrations are therefore reported to be below the lowest calibration standard, multiplied by the dilution factor.
The turbidity of the eluates was < 0.2 NTU. According to this, no undissolved particles were detected in the eluates.
Since no test item was detected in the fraction collected from the column, column material was analysed to demonstrate that the carrier material still contained test substance after elution with water. The test item was detected and therefore confirmed that carrier material still contained test substance.
Applicant's summary and conclusion
- Conclusions:
- The concentration analysed in the samples from the blank column were comparable with the concentrations found in the samples from the loaded column at both flow rates. The analyzed concentrations are therefore reported to be below the lowest calibration standard, <0.02 mg/L.
The turbidity of the eluates was < 0.2 NTU. According to this, no undissolved particles were detected in the eluates. - Executive summary:
The column elution method was applied for the determination of the water solubility of Carrier FK-800. An inductively coupled plasma method with triple quadrupole mass spectrometric detection (ICP-MS/MS) for the quantitative analysis of Fe of the test item in water was developed.
The water solubility of the test itemat 20°C was <0.02 mg/L. The pH of the aqueous samples was 6.1 and 6.2.
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).
