TL;DR: In this article, the isotopic abundances of atmospheric Ar were determined using a dynamically operated isotope ratio mass spectrometer with minor modifications and special gas handling techniques to avoid fractionation.

TL;DR: Amorphous Ga 2 O 3 films have been grown on Si(100) substrates by metal organic chemical vapor deposition (MOCVD) using gallium isopropoxide, Ga(O i Pr) 3, as a single precursor.

TL;DR: In this paper, the authors measured the line shapes of the moderated H atom Doppler profiles as well as the concentrations of D atoms produced in the reactive collisions between the H atoms and D2 or D2O reagents.

TL;DR: In this article, an analytical system for simultaneously monitoring laser-ablation mass spectra and laser-induced breakdown spectra for solid sample has been developed, where the performance of the developed system is evaluated by measuring characteristics such as lifetime of ions inside the plasma and laser power dependence of mass resolution for solid samples.

TL;DR: In this paper, the reproducibility of the NDIR measurement is 0.17 ± 0.01 μmol/mol, which is in excellent agreement with the theoretically predicted value of 0.06 µm/mol with a 95% confidence level, and the data are consistent within uncertainty (calibration line was obtained by the best secondary polynomial least squares fit).
