Study design

HPLC method

Details on study design: HPLC method:

The HPLC is performed on analytical columns packed with a commercially available cyanopropyl solid phase containing lipophilic and polar moieties.A moderately polar stationary phase based on a silica matrix is used.
While passing through the column along with the mobile phase the test substance interacts with the stationary phase. As a result of partitioning between mobile and stationary phases the test substance is retarded. The dual composition of the stationary phase having polar and non-polar sites allows for interaction of polar and non-polar groups of a molecule in a similar way as is the case for organic matter in soil or sewage sludge matrices.
This enables the relationship between the retention time on the column and the adsorption coefficient on organic matter to be established.
Since only the relationship between the retention on the HPLC column and the adsorption coefficient is employed for the evaluation, no quantitative analytical method is required and only the determination of the retention time is necessary.

column: cyanopropylic
Mobile phase: methanol/water = 55/45% v/v
