Analytical method transfers are certainly among the most discussed topics in the GMP regulated sector. However, they are surprisingly little regulated in detail. General information is provided by USP, WHO, and ISPE in particular. Most recently, the EU emphasised the importance of analytical transfer by including it in their draft of the revised GMP guideline. In this position paper, further di...

in this paper, we give an analytical approximate solution for an integro- differential equation which describes the charged particle motion for certain configurations of oscillating magnetic fields is considered. the homotopy analysis method (ham) is used for solving this equation. several examples are given to reconfirm the efficiency of these algorithms. the results of applying this procedure...

A sensitive liquid chromatographic method for the determination of doxycycline in animal tissues has been prepared and validated. The extraction of the analyte from biological matrix was performed with the solution of oxalic acid and ethyl acetate. The samples were cleaned up by solid phase extraction (SPE) procedure using a carboxylic acid cartridge. Chromatographic separation was carried out ...

In this study elements of validation of headspace GC method of determination of residual methanol, n-pentane, ethanol, tert-butylamine, 2propanol, acetonitrile, dichloromethane and toluene in pharmaceutical substance are presented. Validation of the method included: selectivity, system precision, method precision, accuracy (recovery), limits of detection and quantitation (in substance), robustn...

With increasing concern toward environmental protection, enterprises have become more and more responsible for their products reducing pollution and damage. Green supply chain management (GSCM) considers a systematic and integrated approach for companies to maintain their sustainability and competitiveness in the market. Among issues of GSCM, green supplier selection is an important issue in im...

A method is described for assessing occupational exposures to chromium aerosols; it involves four procedures. The first, proton induced X-ray emission (PIXE), measures the total chromium. The second, electron spectroscopy for chemical analysis (ESCA), measures the oxidation state of the particle surfaces, and the third, which uses sym-diphenylcarbazide (DPQ, measures the proportion of water-sol...
