Effects of H2O- and O2-containing He carrier gases on the 206Pb/238U system bias and down-hole fractionation in LA-ICPMS of zircon

Autor: Detlef Günther, Simon E. Jackson, Joachim Koch, Steffen Allner

Publikováno v: Journal of Analytical Atomic Spectrometry. 32:2238-2245

This paper deals with the effects the addition of H2O or O2 to He aerosol carrier gas has on 206Pb/238U ratios during laser ablation inductively-coupled plasma mass spectrometry (LA-ICPMS) of natural zircon and synthetic silicate glass. The following

High-Speed, High-Resolution, Multielemental LA-ICP-TOFMS Imaging: Part II. Critical Evaluation of Quantitative Three-Dimensional Imaging of Major, Minor, and Trace Elements in Geological Samples

Autor: Gunnar Schwarz, Marcel Burger, Detlef Günther, Daniel Grolimund, Simon Burgener, Alexander Gundlach-Graham, Luzia Gyr, Hao A. O. Wang, Steffen Allner, Bodo Hattendorf

Publikováno v: Analytical Chemistry

Here we describe the capabilities of laser-ablation coupled to inductively coupled plasma time-of-flight mass spectrometry (LA-ICP-TOFMS) for high-speed, high-resolution, quantitative three-dimensional (3D) multielemental imaging. The basic operating

A microfluidic vesicle screening platform: monitoring the lipid membrane permeability of tetracyclines

Autor: Phillip Kuhn, Klaus Eyer, Petra S. Dittrich, Dario Lombardi, Steffen Allner

Publikováno v: Analytical Chemistry

For many drugs including antibiotics such as tetracyclines it is crucial that the molecule has the ability to quickly and passively permeate lipid membranes. Hence, the understanding of the permeability in relation to the molecular structure is an im

Accelerated evaporation of microdroplets at ambient conditions for the on-line analysis of nanoparticles by inductively-coupled plasma mass spectrometry

Autor: Detlef Günther, Sabrina Gschwind, Joachim Koch, Steffen Allner, Henry P. Longerich, Luca Flamigni

Publikováno v: Journal of Analytical Atomic Spectrometry. 28:1707

The helium-assisted evaporation of pure, saline, and nanoparticle (NP)-containing microdroplets (∅droplet = 40–50 μm) at ambient conditions was studied. To quantify the liquid-to-gas mass transfer water droplets experience during evaporation, th
