“…[8] Metoprolol Propranolol HF-LPME with in situ derivatization GC-MS ND 0.08 0.05 [9] Metoprolol Propranolol [25] Carvedilol DLLME HPLC/UV 14 4 methods are greatly needed. Recently, salting-out extraction, which is a type of homogeneous LLE has received considerable attention by bioanalysts [57]. Salting-out assisted LLE (SALLE) is performed by more polar solvents (such as acetonitrile, acetone and so on), which are water miscible.…”

“…According to the current state of the knowledge, the same may be true for WAR, i.e. the reports on interactions between WAR and chosen CDs types support this assumption .…”

“…One year later, the same research group released the method allowing the enantioselective separation of several WAR metabolites, also with the use of HS‐β‐CD . The usefulness of sulfo‐butyl ether β‐CD, single‐isomer amino β‐CD derivatives, and other methods involving dimethyl‐β‐cyclodextrin and HS‐β‐CD, have also been reported .…”

“…However, it is not always the case. In the following three cases, phase separation can occur for the acetonitrile-water system: enough amount of salt being added to the mixture solution, [7][8][9][10] enough amount of sugar being added to the mixture solution, [11,12] or the mixture solution being kept at subzero-temperature (À10 C $ À40 C) for an appropriate period of time. [13,14] Accompanying phase separation, the relatively hydrophobic analytes are extracted into the upper acetonitrile-rich phase and the relatively hydrophilic analytes remain in the lower water-rich phase.…”
