“…During element atomization processes at high temperatures (such as those occurring in a graphite furnace), atomic recombination processes occur that result in the formation of diatomic transient molecules. Many spectral characteristics of such molecules, including isotopic effects, are well documented in the literature, 23,26 which can serve as a starting point for program optimization. According to the data available, we selected the X 1 Σ → A 1 Π (0,0) vibronic transition at 195.74 nm 26 for optimizing the formation method for the BF molecule, which, at least in theory, should be the most sensitive transition available and measurable with our spectrometer.…”

“…Boron and boron isotopes were determined through formation of the BF molecule and monitorization of its absorbance. In particular, two vibronic transitions within the X 1 Σ → A 1 Π electronic transition were monitored for this molecule, 26 and each one of them was used either for the elemental determination of B or for the determination of B isotopes.…”

“…The molecular emissions that form the continua could be due to the metal-halogen diatomic emissions (which was required by the selection criteria), the diatomic halogen emissions as all halogen gases have reported emissions in the visible region [29] or a combination of both.…”

In this paper we describe the design of a strategy based on a number of selection rules that could potentially lead us to the identification of materials that will replace mercury and play the role of the active medium in low pressure discharge lamps. The selection rules focus on the emission and thermodynamic characteristics of species as well as safety considerations and the strategy is by no means a complete solution but a logical approach to the solution based on available sources and databases. We experimentally test the first candidates with promising results and we describe trends seen in the periodic table in terms of emissions and the limitations posed by the stoichiometry of the plasma reactions.

“…In order to do so, the NIST Atomic Spectra Database [30] was used for the identification of atomic lines in the tissue spectra. Molecular bands were identified using data for diatomic molecules presented in the book 'The Identification of Molecular Spectra' from Pearse and Gaydon [31] or by comparison to simulated molecular bands using the program code LIFBASE [32]. Differences in the emission spectra from different tissues were investigated by plotting them as an overlay as shown in figure 3 in the results section.…”

Argon plasma coagulation is a promising new approach to combat obesity. During the procedure, a large area of the gastric lamina mucosae and the parietal cells that are located in this layer are ablated. This reduces the secretion of the hormone ghreline, which is known to play a major role in inducing appetite. One hypothesis is that this procedure partly suppresses the feeling of hunger which lowers the food-intake and body weight effectively. To rule out side effects, the treatment of other structures of the gastric wall that are much more sensitive to thermal injury, such as the tela submucosa and the lamina muscularis propria, needs to be avoided. The possibility of layer specific tissue differentiation is explored in this work using optical emission spectroscopy on ex vivo human stomach tissue. The optical emission generated during the plasma treatment of each layer is measured with two different spectrometers. The three main layers of the gastric wall can be differentiated by specific emissions lines of electrolytic ions and trace elements. In order to evaluate the diagnostic quality of this method a linear support vector classifier is used to differentiate the three layers against each other on the basis of these emission lines of these elements. This differentiation between ‘mucosa’ and ‘submucosa’ results in a sensitivity of up to 82% and specificity of up to 92%. However, a lower sensitivity and specificity is found for a classification between ‘submucosa’ and ‘muscularis’ which implies that a classification between ‘mucosa’ and ‘not mucosa’ would be a much more suitable classification for a later clinical application.
