Almost hundred years after the first demonstration of exact mass determination of chemical elements by J. J. Thomson’s in 1912, the method discovered by him – mass spectrometry – reached a high level of development in different fields of science and applications to life sciences, technology, medicine and public life. New aspects of ionization of molecules from all aggregate states contributed l...

In this study, a low background gamma-ray spectrometer based on a Hyper Pure Germanium detector was used to determine the activity concentrations of natural radionuclides in soil samples from various locations within the Ruseifa municipal landfill in Jordan. The chemical composition of the samples was also determined using a Wavelength Dispersive X-Ray Fluorescence Spectrometer. The maximum and...

Laser-induced breakdown spectroscopy (LIBS) has been popular in elemental analysis for various kinds of samples due to its rapid and in-situ measurement using simple equipment. However, quantitative analysis by LIBS is still inferior to conventional element analysis methods in sensitivity and accuracy. In this paper improvement in LIBS is attempted applying computational processing to low-resol...

Introduction: As LIBS has been applied to a wider and more useful range of samples, it has been realized that signals generated with the laser plasma are highly dependent upon the matrix from which they have been ablated. In this case, analytical results dependence on physical properties of the sample. This at times leads to the paradoxical situation where precisely matrix matched calibration s...
