Calculation
1. Capacity factor
The capacity factor was determined using the following equotation:
k=tr-t0/t0 (Equotation 1)
where:
k = capacity factor
tr= retention time (min)
t0= dead time (min)
2. Results
2.1 Definitive test
Calibration
The retention times of water and the retention times, capacity factors (k) and log10POW values for the reference standards are shown in the following two tables:
Dead time | Mean retention time [min] |
water | 1.934 |
Standard | Mean retention time [min] | Capacity factor [k] | Log10k | Log10POW |
Toluene | 3.660 | 0.89245 | -0.0494 | 2.7 |
Naphthalene | 4.698 | 1.42916 | 0.1550 | 3.6 |
Biphenyl | 5.182 | 1.67942 | 0.2252 | 4.0 |
Lauric acid | 5.441 | 1.81334 | 0.2585 | 4.2 |
Dibenzyl | 6.765 | 2.49793 | 0.3976 | 4.8 |
Triphenylamine | 7.971 | 3.12151 | 0.4944 | 5.7 |
A calibration curve was constructed from the retention time data of the water and reference standard solutions (see attached full study report). The capacity factors (k) for th reference standards were calculated using Equotation 1 (see above). Log10POW values of the reference standards are those quoted in Method 117 of the OECD Guidelines for Testing of Chemicals, 13 April 2004.
Partition coefficient of the sample
The retention times, capacity factors and log10POW values determined for the test sample are shown in the following table:
Injection | Retention time [min] | Capacity factor [k] | Log10k | Log10POW |
1 | >30 | >14.5 | >1.16 | >6.5 out of range |
2 | >30 | >14.5 | >1.16 | >6.5 out of range |
The HPLC method enables partition coefficients to be estimated in the log POW range 0 to 6.
2.2 Conclusion
- Log10POW: >6.5
- Partition coefficient: >3.16 x 106
Applicant's summary and conclusion
- Conclusions:
- The partition coefficient of the test material has been determined to be greater than log10POW > 6.5 (at 40°C and pH7)
