Atomic absorption spectrophotometry of chromium in serum and urine with a modified Perkin-Elmer 603 atomic absorption spectrophotometer.
Modification of a Perkin-Elmer 603 atomic absorption spectrophotometer by adding a high-intensity tungsten-halogen lamp for background correction significantly improved the detection limit for elements that have analytical wavelengths in the near-ultraviolet and visible regions. Chromium in human serum and urine can be measured, with a simplified sample-handling technique, in concentrations of ...
متن کاملAssembly of a fast multi resolution spectrophotometer system for simultaneous measurement of absorption and luminescence spectra
In this work, the design and assembly of a dual spectrophotometer system capable of measuring the absorption as well as time resolved luminescence spectra of liquid, gaseous, or solid samples are reported. The system incorporates a 1024×376 elements coupled charge detector (CCD) capable of monitoring changes in optical spectra with time delays as short as few microseconds time scale. Such a des...
متن کاملQuantification of Heavy Metals and Minerals in Selected Indian Medicinal Plants Using Atomic Absorption Spectrophotometer
Medicinal plants form the basis of sophisticated traditional medicine system that has been in existence for thousands of years, which continue to provide mankind with new remedies. Herbal plants are consumed worldwide for the treatment of several diseases and such plants are the important source of raw material for pharmaceutical industries. As a micronutrient, heavy metal plays an essential ro...
متن کاملAutomated, simultaneous microdetermination of calcium and magnesium by atomic absorption.
A procedure is described for the simultaneous, automatic determination of serum calcium and magnesium with the AutoAnalyzer, and a dualchannel, double-beam atomic absorption spectrophotometer, the IL Model 153. Advantages over existing procedures include a high rate of analysis (90 samples or 180tests per hour) and low sample consumption (a total of 30 l for both determinations). We have compar...
متن کاملAluminum Determination for Tri-calcium Phosphate (TCP) Anhydrous Powder by Flame Atomic Absorption Spectrophotometer
Tricalcium Phosphate Anhydrous Powder typically contains 300 to 400 mg/Kg (w/w) of aluminum. This level can be determined utilizing AAS and standard based on known standards. In this study, we have determined the amount of aluminum metal present in sample of Tricalcium Phosphate Anhydrous Powder using Atomic Absorption Spectrophotometer (AAS). The method has high precision and accuracy. The res...
