Determination of S-amlodipine in Human Plasma Using Tizanidine as Internal Standard by Lc/Ms/Ms Method

simultaneous spectrophotometric determination of amlodipine and atorvastatin in commercial tablet by h-point standard addition method

Determination of copper and zinc in blood plasma by ion chromatography using a cobalt internal standard.

Ion chromatography was used to detect levels of copper and zinc in blood plasma from renal dialysis patients on continuous ambulatory peritoneal dialysis (CAPD) and haemodialysis (HD). The developed method used cobalt as an internal standard and when combined with the standard additions method improved the overall precision of the results by between -0.3 and 6.0% and -0.8 and 5.7% for copper an...

Spectrofluorimetric determination of amlodipine in human plasma without derivatization

A rapid and sensitive spectrofluorimetric method was developed for the determination of amlodipine (AD), a calcium channel blocker, in the plasma. The type of solvent, the wavelength range, and the range of AD concentration were selected to optimize the experimental conditions. The calibration curves were linear (r2 ≥0.997) in the concentration range of 0.1-12.5 ppm of AD. The limit of quantita...

Determination of L- Ascorbic Acid in Plasma by Voltammetric Method

Voltammetric techniques have been considered as important methods among the analytical techniques used for the identification and determination of trace concentrations of many biological molecules such as L-ascorbic acid (AA). L-ascorbic acid is an electro-active molecule, though it is difficult to determine its value directly with a majority of electrodes made of carbon and transition metals, ...
