values for the reference standards are shown in the two following
Retention time (mins)
Mean retention time (mins)
Capacity factor (k')
2.88 x 10-2
The retention times, capacity factor
and log10Koc value determined for the sample are
shown in the following table:
-2.27 x 10-2
The test item was determined to have a
mobility class of very high.
Adsorption/Desorption coefficient of Trimethylolethane was undertaken
using a HPLC screening method, designed to be compatible with Method C19
Adsorption Coefficient of Commission Regulation (EC) No 440/2008 of 30
May 2008 and Method 121 of the OECD Guidelines for Testing of Chemicals,
22 January 2001.
The test system utilised a high
performance liquid chromatograph and a commercially available
cyanopropyl reverse phase HPLC column containing lipophilic and polar
moieties was used.
adsorption coefficient (Koc) of the test item has been
determined to be less than 17.8, log10Koc <1.25. The
test item was determined to have a mobility class of very high.
