Abstract: A quadrupole ion trap device has a field adjusting electrode located outside the trapping region adjacent the aperture in the entrance end cap electrode, and optionally adjacent the aperture in the exit end cap electrode. The field adjusting electrode(s) controls field distortion in the vicinity of the apertures. By appropriately setting the voltages on the field adjusting electrodes the efficiency and resolution of operational processes such as ion introduction, precursor ion isolation and mass scanning can be improved.

Abstract: Lecithin-type liposomes are stabilized with quaternized alkyated polymers, such as steardimonium hydroxyethylcellulose, to provide excellent stability for cosmetic and pharmaceutical formulations. Temperature, storage, solvent, and acidity stability are described. The stabilized liposomes can serve as vectors for alpha-hydroxy acids and showed no aggregation even after 4 months of storage at pH 2.
