Determination of Arsenic in the Rainbow Trout Muscle and Rice Samples
Czech Journal of Food Sciences, 2009 The content of arsenic was determined in the rainbow trout muscle (Oncorhynchus mykiss) and in rice samples. The method of atomic absorption spectrometry with hydride generation (HG-AAS) in graphite furnace was used for total arsenic determination ...

Experimental Access to Observing Decay from Extremely Long-Lived Metastable Electronic States via Penning Trap Spectrometry [PDF]
arXiv, 2023 Long-lived ionic quantum states known as metastable electronic states in highly-charged ions (HCIs) are of great interest in fundamental physics. Especially, it generates transitions with very narrow natural linewidth which is a promising candidate for use in the next generation HCI atomic clocks to reach an accuracy below $10^{-19}$.

Analysis of Trace Elements in Human Brain: Its Aim, Methods, and Concentration Levels
Frontiers in Chemistry, 2019 Trace elements play a crucial role in many biochemical processes, mainly as components of vitamins and enzymes. Although small amounts of metal ions have protective properties, excess metal levels result in oxidative injury, which is why metal ion ...

Trapping and sympathetic cooling of conformationally selected molecular ions [PDF]
arXiv, 2023 We report the generation, trapping and sympathetic cooling of individual conformers of molecular ions with the example of cis- and trans-meta-aminostyrene. Following conformationally selective photoionization, the incorporation of the conformers into a Coulomb crystal of laser-cooled calcium ions was confirmed by fluorescence imaging, mass spectrometry

Rotational State Analysis of AlH+ by Two-Photon Dissociation [PDF]
J. Mol. Spectrosc. 300, 108 (2014), 2014 We perform ab-initio calculations needed to predict the cross-section of an experimentally accessible (1+1') resonance-enhanced multiphoton dissociation (REMPD) pathway in AlH+. Experimenting on AlH+ ions held in a radiofrequency Paul trap, we confirm dissociation via this channel with analysis performed using time-of-flight mass spectrometry.

Improvements and simplifications in in-gel fluorescent detection of proteins using ruthenium II tris-(bathophenanthroline disulfonate): the poor man's fluorescent detection method [PDF]
Proteomics 11, 2 (2011) 324-8, 2011 Fluorescent detection of proteins is a popular method of detection allying sensitivity, linearity and compatibility with mass spectrometry. Among the numerous methods described in the literature, staining with ruthenium II tris(bathophenanthroline disulfonate) is particularly cost-effective, but slightly cumbersome owing to difficulties in the ...
