Taschenbuch. Etat : Neu. Neuware - In this book, two modified QuEChERS methods based on sol-gel hybrid MTMOS-TEOS and Al2O3 as a new/alternative dSPE sorbent materials to PSA for determination of acrylamide in Sudanese food using direct GC-MS in SIM mode and UHPLC-Orbitrap-MS analysis respectively were successfully developed and first reported. Work using QuEChERS method based on sol-gel hybrid MTMOS-TEOS as dSPE material followed by GC-MS analysis gave comparable results to those obtained from previous studies using PSA as clean-up sorbent. Acrylamide was detected in fried potato and fried eggplant but taamia, minnan, ab.rae/hilumur and gorassa were free from acrylamide. Precursors of acrylamide (amino acids and reducing sugars) were determined in Sudanese foods raw materials. An inexpensive CE-UV method with NBD-Cl as pre-column derivatization agent was proposed for separation and determination of amino acids in food samples. Various derivatization conditions were optimized and then the method was validated. Also the levels of reducing sugars fructose, glucose, sucrose and maltose were determined in foods using HPLC-RI.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book demonstrates the potential of 1,2-Naphthoquinone-4-sulphonic acid sodium salt (NQS) as an analytical reagent for the analysis of pharmaceutical drugs bearing amine group in their pharmaceutical formulation. Simple, fast and reliable spectrophotometric methods were developed and validated for the determination of various pharmaceuticals bearing amine group ,cephalosporin, fluoroquinolones, cardiovascular drugs and antimalarial. Different variables affecting the reactions between the NQS and the drug bearing amine group such as pH, concentration of NQS, temperature, and reaction time were carefully studied and optimized. The methods developed were validated with respect to accuracy, precision, linearity, selectivity, sensitivity, limit of detection, and limit of quantification according to the International Conference of Harmonization (ICH) guidelines for validation of analytical procedures. The proposed methods were successfully applied to the determination of each drug in its pharmaceutical dosage form with a high accuracy and precision, without the need for complex sample preparation such as extraction steps prior to the drug analysis. and without interference from 116 pp. Englisch.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Capillary electrophoresis (CE) has now become one of the most advanced separation techniques for pharmaceutical analysis. A major advance for CE is its recognition by various regulatory authorities. A general monograph on CE is now included in the United States Pharmacopoeia (USP, which has also been published in the European Pharmacopoeia (EP) and Japanese Pharmacopoeia (JP).The generally short duration of method development, the simple instrumentation and the use of small sample and electrolyte volumes are, of course, interesting from financial and environmental perspectives The main application areas of CZE in drugs analysis are in chiral separation, main component assay and impurity determination. This work demonstrates the potential of CE as a routine analytical separation technique for the analysis of non chiral, chiral and impurities in pharmaceuticals formulation of fluoroquinolones and primaquine.…
