“…The relative concentrations of different elements, thus obtained in the present experiment for the above standard samples are compared with the certified concentrations supplied by NIST. Good agreement [10] within experimental uncertainties is observed and this shows the reliability of the present experimental system and use of GUPIX software package in the data analysis [11].…”

In the chemical characterization of charnokite is well investigated by using PIXE and other analytical techniques, but PIXE not given information about some of elements completely, because every technique including PIXE has proper limitations. To obtain the complete geochemical explanation of matrix charnockite composition, the experimental factors behind missing elements in PIXE at 3 MeV techniques with comparison must known and hence are used for the analysis of matrix compositions related to the earth materials like charnockite. In this study, the results obtained from PIXE compared with other analytical techniques and experimental factors of PIXE are discussed. By investigating the geochemical nature of complex charnockite material, the experimental factors which are related to the missing elements in this study of wide range of elements obtained from PIXE spectrum through the previous analytical techniques have been discussed.

“…To prove the reliability of the experimental part and other factors, the PIXE spectrum was obtained with NIST certified, standard reference material. In the case of PIXE analysis (15) , the characteristic X-ray wavelengths emitted by the target composition can be easily quantified by gathering them through the Si (Li) detector (typical energy range = 2-20 keV) (16) (17) . https://www.indjst.org/…”

Background/Objectives: The demand for exact quantification analyses in complex ore assemblages is increasing rapidly as mineral processing studies become more sophisticated. In response to this need, an Electron Micro Probe Analysis and Proton Induced X-ray Emission complementary based analytical tool procedure for the chemical characterization of minerals was employed to study the metamorphic rocks. Methods : In this work, we compare the quantitative analysis of high-grade metamorphic rocks by proton induced X-ray emission (PIXE) with that of the previous analyses by electron probe microanalysis (EPMA). During this investigation, the PIXE analytical method on a nuclear microprobe was added to the previously well-known EPMA for the chemical quantification of high-grade metamorphic rocks from the Charnockite Hill, Visakhapatnam, A.P., India. For the evolution and geochemical characterization of the metamorphic rocks, the above two methods are compared and discussions are made with respect to certain elements. Findings: Particle-induced X-ray emission is well-matched except for certain elements for the chemical characterization of metamorphic rocks belonging to earth material samples. This comparison with EPMA demonstrates the elemental quantification characteristics for such analyses. Not only is an exploratory study of proton induced X-ray emission benefit presented, but also a synopsis of comparison with electron probe microanalysis aimed at a responsible reply to metamorphic rock analytical questions. Novelty: The complementary technique, especially EPMA, is required to fill the elemental gaps that are not determined in the case of matrix complex charnockite compositional analysis by PIXE with 3MeV and a Si (Li) detector.
