Additional information

At pH 4 the majority (approx. 80% by chromatographic area) of the components of the test material were found to have retention times of greater than 4.6 minutes corresponding to LogKoc values of greater than 3.9. The main chromatographic component at approximately 5.4 minutes was determined to have a log10Koc value of 4.6.
