Combined use of quantitative ED-EPMA, Raman microspectrometry, and ATR-FTIR imaging techniques for the analysis of individual particles.
In this work, quantitative energy-dispersive electron probe X-ray microanalysis (ED-EPMA) (called low-Z particle EPMA), Raman microspectrometry (RMS), and attenuated total reflectance Fourier transform infrared spectroscopic (ATR-FTIR) imaging were applied in combination for the analysis of the same individual airborne particles for the first time. After examining individual particles of microm...
متن کاملDetermination and Application of Trace Elements
It is a well known fact that minera l plays an important role in the nutrition of animal and plant. The t race elements, which are a part of the mineral and exi st in a very small amount in the living bodies, include not only essential elements but also harmfu l and useless elements. In the researches up until now, physiological significance or essentiality for living body of such elements as c...

15 صفحه اولElimination of Chemical and Spectral Interferences in Measurement of Trace Elements in Urine and Blood by Combined Electrodeposition-Electrothermal Atomic Absorption Spectrometry
A combined electrodeposition-ETAAS technique has been applied to the analysis of Pb, Cd, Co, Ni, Cr and Mn in biological samples in order to overcome interferences and to minimize sample pretreatment. It requires minimal sample preparation with the electrolysis process aiding partial decomposition of the organic matrix, adequate for the release and deposition of trace elements. In an initia...
متن کاملThe concentration of heavy trace elements in pigment and cholesterol humangallstones: Comparative studies by PIXE analysis.
Background: The method of proton induced X-ray emission (PIXE) has been widely used as a sensitive technique to trace elemental analysis in both biological and medical fields. The sensitivity of this powerful method is in the order of ppm .The aim of this work is to analyze structural composition of 4 heavy trace elements with Z greater than 24 (Mn, Fe, Cu, Zn) in two kinds of gallstones and to...
