Description of key information

During testing it was observed that these hydrocarbon structures did not elute from a cyanopropyl solid phase HPLC column during the 45 minute run time. The adsorption coefficient of duplicate determinations of EXP0700332 test item was therefore determined to be as follows:

Log10 Koc of EXP0700332 >10.04 (retention time greater than 45 minutes run time

Koc of EXP0700332 > 1.10 x 10^10

Alternatively, the adsorption coefficient may be expressed as being greater than that of 4,4’-DDT, the latest eluting reference standard used. Since 4,4’-DDT has a theoretical adsorption coefficient of 5.63, it may be stated that for EXP0700332:

Log10 Koc >5.63

Koc >4.27 x 105
