A novel experimental approach using the rotating sample system (RSS) is proposed here for the determination of the critical micelle concentration (CMC) of surfactants. The RSS has been conceived in our laboratory as a convection platform for physicochemical studies and analyses in microliter-sized sample drops. The scheme allows for vigorous rotation of the(More)
This work describes the stability of the selected in situ solutions for ophthalmic delivery of naphazoline hydrochloride ( FF17, FF18) and antazoline phosphate ( GG17 and GG18) based on the pH triggered concept using Carbopol 940 and HPMC K4M. The formulations were evaluated for their pH, isotonicity, gelling capacity, rheological characteristics, in vitro(More)
The Rotating Sample System (RSS) has been conceived in the authors' laboratory as a convection platform for microliter-sized solution volumes. Convection is achieved by rotating a small drop of sample on a stationary substrate by humidified gas jets directed tangentially at the drop base with the working electrode and a liquid junction embedded in it.(More)
