Direct determination of total serum phospholipid by x-ray fluorescence.
An x-ray fluorescence method for measurement of total serum phospholipid is described. A Folch extract of 1 ml of serum is evaporated and deposited on a paper disc by washing with chloroform. A coefficient of variation of 4% was obtained for samples containing at least 1 micromole of lipid, as phosphorus. The major advantage of the method is its speed (5 mm/sample) in comparison to the phosphom...
متن کاملQuantitative Determination of Free Lime Amount in Steelmaking Slag by X-ray Diffraction
Steelmaking slag is a by-product of steel making. It has been reused as a material for civil engineering, pavement construction etc. For such applications, it is extremely important to evaluate the amount of free lime, which has the chemical form of calcium monoxide (CaO) and can cause the failure of mechanical properties by volume expansion through absorption of water or carbon dioxide gas. So...
متن کاملDetermination of cristobalite phase content in ceramic cores using various X-ray quantitative phase analysis methods
The aim of this research is to investigate different X-ray based quantitative phase analysis methods for determination of cristobalite phase content in ceramic cores. For this purpose, four popular routes including peak absolute intensity method, relative intensity ratio method, direct or calibration method and internal standard (or Alexander-Klug) method have been chosen. Some control samples ...
متن کاملMultielement analysis of soft drinks by X-ray fluorescence spectrometry.
Several commercial soft drinks and respective plastic bottles were analyzed for their multielement contents employing the synchrotron radiation total reflection X-ray fluorescence spectrometry technique (SRTXRF). The SRTXRF method has been developed and validated, and about 20 elements were detected in the investigated samples, including some trace elements, which can be toxic for human beings,...
متن کاملAnalysis of Tclp Extracts by X-ray Fluorescence
The toxicity characteristic leaching procedure (TCLP) is one test used by the U.S. Environmental Protection Agency (EPA) to determine if a waste material is hazardous; the TCLP test is widely used by the environmental testing community. The elements of concern for toxicity are arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver. As an environmental forensic laboratory, the N...
