Kd was calculated from Kd = Kd'/CP where Kd' = ksorp/kdesorp. CT-model is the CT used in fitting. Nominal Ctotal er den nominelle, totale koncentration i reagensglassene beregnet ud fra den aktivitet, som er bestemt i arbejdsopløsningerne (se Table 4.7). Kd blev beregnet ud fra Kd = Kd'/CP hvor Kd' = ksorp/kdesorp. CT-model er den CT, som er brugt ved tilpasningen (fitting).
