Multi-step phase-cycling in a free-electron laser-powered pulsed electron paramagnetic resonance spectrometer
12-Jun-2018 | Christopher Blake Wilson; Samuel Aronson; Jessica Ann Clayton; Steffen J Glaser; Songi Han; Mark Sherwin, Physical Chemistry Chemical Physics, 2018
Electron paramagnetic resonance (EPR) is a powerful tool for research in chemistry, biology, physics and materials science, which can benefit significantly from moving to frequencies above 100 GHz. In pulsed EPR spectrometers driven by powerful sub-THz oscillators, such as the free electron laser ...
Multi-spectrometer calibration transfer based on independent component analysis
30-May-2018 | Yan Liu; Hao Xu; Zhenzhen Xia; Zhiyong Gong, Analyst, 2018
Calibration transfer is indispensable for practical applications of near infrared (NIR) spectroscopy due to the need for precise and consistent measurements across different spectrometers. In this work, a method for multi-spectrometer calibration transfer is described based on independent ...
Application of microsecond pulsed glow discharge to modern commercially available optical emission spectrometers for bulk elemental analysis
30-May-2018 | M. Voronov; V. Hoffmann, Journal of Analytical Atomic Spectrometry, 2018
Microsecond Pulsed Glow Discharge (μs-PGD) was applied to commercially available spectrometers specified for OES elemental analysis with Grimm type sources, in order to have a look at the benefits which PGD can bring for practical bulk analysis. Intensities of more than 70 spectral lines of ...
Multi-element ion-exchange chromatography and high-precision MC-ICP-MS isotope analysis of Mg and Ti from sub-mm-sized meteorite inclusions
28-May-2018 | K. K. Larsen; D. Wielandt; M. Bizzarro, Journal of Analytical Atomic Spectrometry, 2018
The analytical improvement of new generation mass spectrometers has reached a level required for high-precision isotope analysis of very small and unique natural samples. The multi-element isotopic signatures of meteorite inclusions can potentially provide detailed insight into the origin of our ...
