Book Description
A new room temperature ionic liquid, isopropylammonium formate, IPAF, has been synthesized. Its application as a mobile phase replacement for traditional organic reversed phase-high performance liquid chromatography solvents is demonstrated. Solvent characteristics of IPAF, such as, polarity index, viscosity, and solvent strength are measured. Various van Deemter plots using different mixing approaches of the mobile phase and different columns are compared. The utility of IPAF has been further shown to be a suitable modifier solvent for the separation of cytochrome c from tryptophan. At 50°C, IPAF was able to maintain cytochrome c in its native form during the course of a chromatography separation, while a similar methanol modifier causes denaturation. Our long term goal is to develop a semi-preparative method to separate proteins in their native conformation. A comparison of atomic absorption and molecular spectrophotometry for the use in determining phosphate in an undergraduate teaching environment is also presented.

Book Description
"Felodipine, USP is a dihydropyridine calcium antagonist. The brand names for Felodipine are Feloday, Plendil, and Hydec. It is described as an antihypertensive vasodilator agent. A stability indicating reversed phase high performance liquid chromatography has been developed and validated for the determination of Felodipine in a raw material. Agilent 1100 series high performance liquid chromatography system was used for method development studies. The separation was performed on Phenomenex Synergi C18 (4μm), 150 x 4.6 mm column with flow rate 1 mL/min at 25°C column temperature. Isocratic elution was carried out with mobile phase consisted of Solvent A (25mM mono-basic Potassium Dihydrogen Phosphate, pH 2.5) and Solvent B (50% ACN). The UV detection wavelength was set at 235 nm. The stability study of Felodipine was carried out by forced degradation using hydrochloric acid, sodium hydroxide, hydrogen peroxide, UV light, and heat. The correlation coefficient was 0.9996 which indicates linear regression curve. The percentage recovery of the method was 99-100%. The percentage RSD for method precision for peak area and retention time was 1.12 and 0.42, respectively. (n=6). The LOD and LOQ result was found to be 0.01 ppm and 0.05 ppm respectively. The developed method is specific, linear, precise, accurate, and robust based on validation results according to ICH guidelines."--

Book Description
The Analysis of Explosives surveys the principles of the various analytical methods, describes how these methods are used for the analysis of explosives, and reviews the major analytical work carried out in this field. Organized into 15 chapters, this book begins with the classification of explosives. Subsequent chapters discuss the different methods for the analysis of explosives. The detection and identification of explosive residues and hidden explosives are also explained. This monograph will be useful as a reference book for chemists in analytical and forensic laboratories, as well as a textbook for graduate students in analytical chemistry and forensic sciences.
