DETERMINATION OF RETENTION TIMES
- Quantity of test substance introduced in the column: no information
- Quantity of reference substances: no information
- Intervals of calibration: no information
REPETITIONS
- Number of determinations: 6 for reference substances and 3 for HEPES
EVALUATION
- Calculation of capacity factors k': The capacity factor k´ for every peak was calculated as follows: K'= (tr -to)/to, with tr=retention time and
to=dead time (retention time of sodium nitrate)
- Calculation of retention times: retention time of peaks were used
- Determination of the log Koc value:
The calibration function was drawn up from the six measurements of the capacity factors of the reference items. By plotting the (known) log KOC
values of the reference items against the mean log capacity factors and performing linear regression, a calibration function was obtained.
With the calculated capacity factors for the test item, each log KOC from the three determinations was calculated. Finally, mean and standard
deviation of the log KOC were calculated. - Type:
- log Koc
- Value:
- > 5.63
- Temp.:
- 25 °C
- Details on results (HPLC method):
- - Retention times (mean in minutes) of reference substances used for calibration:

Phenole 2.855
Methylbenzoate 3.241
Naphthaline 4.418
1,2,3-Trichlorbenzene 5.024
Phenanthrene 6.940
DDT 13.955
- Details of fitted regression line (log k' vs. log Koc): log k’ = 0.2052 * logKOC - 0.1476 (r²=0.9989)
- Average retention data for test substance: 2.085 (SD = 0.01) - Validity criteria fulfilled:
- yes
- Conclusions:
- In a GLP-study according to OECD test guideline 121, the log koc of the registered substance was determined as > 5.63.
- Executive summary:
The study was performed using a HPLC with a cyanopropyl chemical bound resin on a silica basecolumn. Six reference items with different retention times were used to produce a calibration curve, since retention time on cyanopropyl columns and KOCare correlated. The reference items were chosen on behalf of the retention time of the test item CARDOLITE NC-513 on the column.
A solvent blank followed by three injections of a solution of the reference items were analysed with HPLC, then three injections of a solution of the test item; and finally three injections of the solution with the reference items, totalling to ten runs.
For each reference item, the capacity factor k’ was calculated from the retention time of sodium nitrate and the retention time of the respective reference item. A calibration function was set up using the literature values for KOCof the reference items and the mean capacity factor of the six determinations. In the graph Log k’ versus Log KOC, linear regression was performed, giving r2= 0.983 and r = 0.992.
The chromatogram of the test item gave eight peaks. With the help of the calibration function log K versus log KOC, the corresponding log KOCs were determined.
As the major peaks lay outside the calibrated range, the log KOCof the test item CARDOLITE NC-513 should be stated as > 5.63.

Using the correlation log k’ / log KOC, the log KOCof the peaks of the test item CARDOLITE NC-513 was estimated as > 5.63 (result of three determinations), as peaks 1 – 5 are minor peaks and peaks 4 – 8 lay outside the calibrated range.

Additional information
The substance has a high adsorption/desorption coefficient, which indicates that it will have high likelihood of partitioning to sediments, organic matter in soil or sludge in the sewer system.
