“…The concentration range selected in this technique is mainly based on two facts. The volatilization behaviour of the analytes and the specification limits of the analytes in that particular matrix as reported in case of U−Pu−Zr alloy and BeO matrices [22,50] . In present investigation, the standards prepared for establishing calibration curves are 5 ppm,10 ppm, 20 ppm, 50 ppm, 100 ppm, 200 ppm, 500 ppm, 1000 ppm.…”

Methodologies have been developed for the chemical quality control of zircon mineral by EDXRF and D.C.Arc carrier distillation technique. EDXRF technique was found to be preferred for major and minor constituents including non‐metal analytes, while D.C.Arc carrier distillation OES was found to be good for minor and trace metallic constituents including low Z elements. A comparative evaluation of the analytical performance (detection limit, sensitivity, precision, linear dynamic range) was performed. A multipoint standardization was carried out using the base material of 1 : 1 SiO2 : ZrO2 powder mixture to establish calibration curves for the analytes after identification of interference free and the best performed emission and X‐ray analytical lines. In zircon sample, Si, Zr and Y were found to be present as major constituent, with Ga, Ca, Ru, Rh, Fe, Mn, Mg, I, S as minor and Zn, Cr, Sn, Li as trace constituents. The total uncertainty of the EDXRF measurements was evaluated. The statistical t‐test analysis was carried out for 10 degrees of freedom with 95 % confidence interval. The experimentally obtained t‐values were found to be lower compared to the corresponding tcri value revealing the reliability of the measurements. Elemental distributions of the analytes were also investigated using five different zircon samples.

A comparative investigation on characterization of ilmenite manuscript was performed by energy dispersive X‐ray fluorescence spectrometry (EDXRF) and carrier distillation direct current arc atomic emission spectrometry (D.C. Arc AES) along with the statistical evaluation of the data obtained. 5 % AgCl was used as carrier in AES to avoid spectral interference arising out of the emission rich matrix elements. An exercise was performed to evaluate the total uncertainty associated with the methodology for characterization of base reference materials. The developed methodologies were validated using synthetic samples. ∼30 % Fe and ∼35 % Ti as major elements alongwith Ca, Mg, Cr, Si, Al, Ni, Mn, V, Zr, Eu, Mo, Na and Cd as minor and trace level were reported in real ilmenite samples. Student t test was performed at 95 % confidence limit with 10 degrees of freedom revealed that the null hypothesis persisted, i. e. the data obtained by both the methods are reliable and within the limit of statistical fluctuation. The F test on variance revealed that all the variance estimated for all the analytes were less than the critical value (Fc=2.98) and hence the variance is also within the statistical fluctuation

A comprehensive evaluation was carried out for elemental characterization of automobile glasses having potential forensic application by Energy Dispersive X‐ray Fluorescence (ED‐XRF) spectrometry and Direct Current Atomic Emission Spectroscopy (DC Arc AES). The methods were optimized and validated using geological certified reference materials and glass standard reference material. Total seventeen elements including five major elements (Si, Na, Ca, Mg and Fe) and twelve minor and trace elements (Al, Ti, V, Cr, Mn, Ni, Cu, Zn, Rb, Mo, Zr and Sr) were found to be present. Though DC Arc AES performed better for minor and trace level determination, however, the precision was evaluated as 15–20 % RSD. On the contrary, ED‐XRF performed better for major elements with 5–10 % RSD. The detection limits for the analytes prone to form refractory oxides on heating were found to be poorer in DC Arc AES compared to ED‐XRF. Statistical analyses were also performed to evaluate the reliability of the data obtained by the optimized methods. As a part of forensic applications, the elemental concentrations of minor and trace elements were utilized for the grouping study of the glass samples by cluster analysis using average linkage method.
