Spatially resolved measurements and plasma tomography with respect to the rotational temperatures for a microwave plasma torch

Spectroscopic diagnostics for evaluation of the analytical potential of argon + helium microwave-induced plasma with solution nebulization

“…All these values are substantially higher than those obtained for pure argon (2580 K) and helium (1990 K) plasmas with solution nebulization. Moreover, these values are higher than those reported for argon MIP for different microwave devices (surfatron: 2570 K, 8 TE 101 : 2500-2750 K, 26 MPT: 3600 K 27 ). The rotational temperatures obtained at low helium content in mixed-gas plasma are also higher than those for argon ICP with solution nebulization (3340-3500 K) 28,29 and for argon MIP with hydride generation (3740 K).…”

Estimation of confidence intervals for radial emissivity and optimization of data treatment techniques in Abel inversion

“…Instead, a variety of mathematical algorithms to fit the raw data and to perform the inversion are employed [9][10][11][12][13][14][15][16]. In the present study, the Nestor-Olsen method was chosen due to its easy computation and widespread use [5,26,28]. In this method, the lateral profile, I(x), is assumed to have axial symmetry with a total of 2N + 1 equally spaced data points.…”

Use of electrolyte cathode glow discharge (ELCAD) for the analysis of complex mixtures

“…This excitation temperature and the OH rotational temperature were both calculated from Boltzmann plots of a collection of lines. 22,23 For OH, the lines were at 308. In both cases, the averages of peak areas from five spectra acquired by scanning the monochromator wavelength were used in the calculations.…”
