the objective of the study was to develop a simple, specific and stability-indicating hplc method for the simultaneous determination of creatine phosphate sodium (cps) and its related substances in pharmaceutical formulation. separation of creatine phosphate sodium from its major process impurities and degradation products was achieved on a hypersil bds c18 column (250 × 4.6 mm, 5 μm) with an a...

A simple and rapid stability indicating method based on capillary zone electrophoresis has been developed and validated for the analysis of buserelin (BUS). The best separations were achieved by using a bare fused silica capillary (75 m i.d.; 65.5 cm total, 57.0 cm effective length), phosphate buffer (pH = 3.00; 26.4 mM), at 35 °C. The sample was hydrodynamically injected at 50 mbar for 5 seco...

High performance liquid chromatography (HPLC) is an integral analytical tool in assessing drug product stability. HPLC methods should be able to separate, detect, and quantify the various drug-related degradants that can form on storage or manufacturing, plus detect and quantify any drug-related impurities that may be introduced during synthesis. Forced degradation studies of new chemical entit...

A novel stability-indicating high-performance liquid chromatographic assay method was developed and validated for valacyclovir in the presence of degradation products generated from forced decomposition studies. A Hypersil ODS C-18 (250 x 4.6 mm, packed with 5 micron) column in an isocratic mode with the mobile phase acetonitrile: phosphate buffer (pH3.6) (50:50%v/v) was used. The flow rate was...

in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
