“…7–9 Therefore, to avoid that, a suitable chemical separation methodology needs to be applied prior to the sample feeding to the plasma for estimation of analytes. 10–14 Though in D.C.Arc atomic emission spectrometry, where solid samples are directly analyzed; physical separation is performed in terms of distillation of analytes in the presence of a suitable carrier such as AgCl. 15–20 However, D.C.Arc carrier distillation is having poorer analytical performance with respect to detection limits, linear dynamic range, sensitivity and more predominantly with respect to precision (in comparison with ICP-OES).…”

Conventional characterization of plutonium contaminated neoprene gauntlets and cellulosic materials are highly difficult not only due to the non-geometric and unconventional nature of the sample, but also the radio-toxicity associated with them. An analytical method based on direct current arc atomic emission spectrometric (D.C.Arc AES) technique was developed for direct determination of 22 metallic impurities in contaminated neoprene gauntlets and cellulose samples. The samples were incinerated to powder form and analyzed against seven point standardization using graphite standards. The interference free best performed emission lines of the analytes were chosen as the analytical lines for establishing the calibration curves required for their estimation. The linear dynamic range, sensitivity, detection limit, precession associated with these analytical lines were evaluated in the graphite matrix. Energy dispersive X-ray fluorescence spectrometry has also been employed for comparative evaluation of the analytical performance of the developed AES based method as well as analysis of the actual samples. D.C.Arc AES based method was found to have 20% precession, while that for EDXRF was 10%. However, elements with lower Z values and lower concentration can only be determined by AES.

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.
