Factorial Design in Optimization of Chromatographic Separation of Ramipril and Its Impurities
(Springer Heidelberg, Heidelberg, 2010)
In this paper optimization of chromatographic retention of ramipril and its five impurities employing factorial design is presented. On the basis of preliminary experiments three factors were chosen as inputs (acetonitrile ...
UPLC Method for Determination of Moxonidine and Its Degradation Products in Active Pharmaceutical Ingredient and Pharmaceutical Dosage Form
(Springer Heidelberg, Heidelberg, 2014)
A simple, rapid, isocratic, stability-indicating reverse phase ultra-performance liquid chromatographic (RP-UPLC) method was developed and validated for the routine analysis of moxonidine in the presence of its degradation ...
Optimization of Artificial Neural Networks for Modeling of Atorvastatin and Its Impurities Retention in Micellar Liquid Chromatography
(Springer Heidelberg, Heidelberg, 2011)
Artificial Neural Networks (ANNs) present a powerful tool for the modeling of chromatographic retention. In this paper, the main objective was to use ANNs as a tool in modeling of atorvastatin and its impurities' retention ...
Multiobjective Optimization Approach in Evaluation of Chromatographic Behaviour of Zolpidem Tartrate and Its Degradation Products
(Springer Heidelberg, Heidelberg, 2011)
Multiresponse optimization methodology in combination with experimental design was employed as a powerful technique for simultaneous optimization of input variables significant for evaluation of chromatographic behaviour ...
GC-ECD Determination of Lindane and Its Impurity alpha-HCH in Pharmaceutical Products
(Springer Heidelberg, Heidelberg, 2010)
A method was developed to determine lindane (gamma-HCH), the widely used organochlorine pesticide, and its impurity alpha-HCH in bulk and pharmaceutical products (shampoo, gel and emulsion). The system was able to successfully ...
An Improved HPLC Method for Simultaneous Analysis of Losartan Potassium and Hydrochlorothiazide with the Aid of a Chemometric Protocol
(Springer Heidelberg, Heidelberg, 2013)
An experimental design method was used for fast, simple, and accurate high-performance-pressure liquid chromatograpy (HPLC) determination of losartan and hydrochlorothiazide in combined dosage forms. This method avoids the ...
