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 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 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...
متن کاملSimple nanosecond to minutes transient absorption spectrophotometer.
We built a transient absorption spectrophotometer that can determine transient absorption spectral changes that occur at times as fast as approximately 200 ns and as slow as a minute. The transient absorption can be induced by a temperature-jump (T-jump) or by optical pumping from the deep ultraviolet (UV) to the infrared (IR) by use of single ns Nd:YAG laser pulses. Our use of a fiber-optic sp...
متن کاملForensics Atomic Absorption Spectroscopy
Atomic absorption spectroscopy Atomic absorption spectroscopy (AAS) was developed in the early 1950’s by Alan Walsh. It works on the principle that certain elements absorb certain wavelengths, and this level of absorption is characteristic of each element. Also, electrons in atoms can only exist in particular energy levels, and when an electron moves to a higher energy level, electromagnetic ra...
