Rapid determination of Dimethoate in some formulations by infrared spectrophotometry

Application of UV-derivative spectrophotometry for determination of some bisphosphonates drugs in pharmaceutical formulations.

A method for determination of alendronate sodium salt, clodronate disodium salt and etidronate disodium salt in pharmaceutical formulation by direct UV-spectrophotometry and/or first and second derivative UV-spectrophotometry via complex formation with Cu (II) ions is described. The calibration graphs are linear in the range 25-600 mmol/L for all the investigated compounds. No interference was ...

Simultaneous Determination of Hydrochlorothiazide and Enalapril Maleate in Pharmaceutical Formulations Using Fourier Transform Infrared Spectrometry

A new Fourier Transform-Infra Red (FT-IR) spectrometric method was developed for assaying hydrochlorothiazide (HCT) and enalapril maleate (ENM) in binary solid pharmaceutical formulations. Multivariate Partial Least Squares (PLS) method was used for calibration of derivative spectral data. Acetonitrile was used as solvent due to its spectral tran...

Paraffinoma confirmed by infrared spectrophotometry.

Investigation and Determination of Osvix by Gold Nanorods by Spectrophotometry

Background and Aims: Osvix drug is an internal brand of Plavix, which is used to prevent blood coagulation in many heart diseases. The aim of the present study was to measure this drug by gold nanorods in optimum conditions and in real samples. Material and Methods: Gold nanorods were synthesized by the seeded-mediated method. Measurement of Osvix drug by gold nanorods was performed by optimizi...

determination of some physical and mechanical properties red bean

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
