Concentrations of oxirane and naphthalene were determined using GC/Mass spectrometer (modelQP201 Plus Shimadzu), in effluent samples from four selected petroleum based industries in Kaduna metropolis, Nigeria, coded as KP, TL, OL(I) and OL(II). Oxirane was detected in the morning, afternoon and evening samples of OL(II), morning and afternoon samples of KP and afternoon samples of TL. While nap...

The present research work discussed the development of a simple, sensitive, rapid, accurate, precise and economical UV Spectrophotometric method for the Validation of Oseltamivir Phosphate in bulk and pharmaceutical dosage form which is based on the measurement of absorption maxima at 217 nm. Double beam U.V visible spectrophotometers, Shimadzu, Kyoto, Japan. Model UV1800 with 1cm matched quart...

A simple, rapid and accurate liquid chromatography - tandem mass spectrometry method was developed and validated for the quantification of acetazolamide in beagle plasma using sulfadiazine as the internal standard. After extraction by acetonitrile, the analytes were separated by a rapid gradient elution with acetonitrile and water as the mobile phase on a SHIMADZU VP-ODS C18 column and then det...

A simple, precise, and accurate stability indicating gas chromatographic method has been developed and validated for assay of Magnesium Valproate. The Chromatographic system used to perform development and validation of this assay method consisted of Shimadzu 2014 G.C. with Flame Ionization Detector and a manual injector. The method was validated for specificity, linearity, precision, accuracy,...

General. 1H and C NMR spectra were measured on Varian Gemini 2000 (300 MHz for H) instruments, and are reported in parts per million (δ) from internal tetramethylsilane or residual solvent peak. IR spectra were recorded on a Shimadzu FTIR-8200, and absorptions are reported in cm. FAB-MS spectra were recorded on JEOL IMS-300 spectrometer. 3-Nitrobenzyl alcohol was used as a matrix for FAB-MS. Me...

With advances in devices and techniques, the success rates of percutaneous coronary intervention(PCI)and endovascular treatment (EVT)remarkablly increased. This increased success has facilitated the pursuit of less invasive procedures, such lower dose of contrast agent, lower exposure, and shorter procedure time. Taking advantage of intravascular imaging techniques such as intravascular ultraso...

A simple, specific, accurate and stability-indicating UV- Spectrophotometric method was developed for the estimation of candesartan cilexitil, using a Shimadzu, model 1700 spectrophotometer and a mobile phase composed of methanol: water in the ratio of 9:1 at wave length (λ(max)) 254 nm. Linearity was established for candesartan in the range of 10-90 μg/ml. The percentage recovery of was found ...

A simple, precise and specific reverse phase high performance liquid chromatographic method has been developed and validated for the determination of raltegravir in blood. The HPLC separation was carried out by reverse phase chromatography on Shimadzu HPLC system consisted of Welchrom 5μ C18 column (250 X 4.6 mm), SPD 10A UV detector and LC 10AD Pumps. Rheodyne injector with 20 μl loop with a m...

Ensuring foods are correctly labelled for ingredients derived from genetically modified organisms (GMOs) is an issue facing manufacturers, retailers, and enforcement agencies. DNA approaches for the determination of food authenticitys often use the polymerase chain reaction (PCR), and PCR products can be detected using capillary or gel electrophoresis. This study examines the fitness for purpos...

Vacuum evaporated films of GexSe80-xPb20 have been characterized by using optical spectroscopy (especially transmission and absorption spectra). The chalcogenide glass of GexSe80-xPb20 has been prepared by melt quenching technique. Thin films of GexSe80-xPb20 are deposited by vacuum thermal evaporation technique on highly clean glass substrates and their optical properties such as refractive in...
