The aim of this newly developed method is to develop a full factorial designed, greener, more sensitive and faster method for estimation of the quaternary mixture either in raw material or dosage form with no interferences of the dosage form additives. The developed method was designed using FFD ...
Full size table Method precision was evaluated through both intra- and inter-day experiments. The intraday precision was evaluated by performing three repetitive injections of the standard solutions containing 16 phenolic compounds in a single day, whereas the three consecutive days were used to evaluat...
