Deep Learning Approach for Dynamic Sampling for Multichannel Mass Spectrometry Imaging [PDF]
arXiv, 2022 Mass Spectrometry Imaging (MSI), using traditional rectilinear scanning, takes hours to days for high spatial resolution acquisitions. Given that most pixels within a sample's field of view are often neither relevant to underlying biological structures nor chemically informative, MSI presents as a prime candidate for integration with sparse and dynamic

Prospects in Analytical Atomic Spectrometry [PDF]
Russian Chemical Reviews, v. 75, pp. 289-302 (2006). [Translated
from Uspekhi Khimii, v. 75, pp. 322-338 (2006)], 2006 Tendencies in five main branches of atomic spectrometry (absorption, emission, mass, fluorescence and ionization spectrometry) are considered. The first three techniques are the most widespread and universal, with the best sensitivity attributed to atomic mass spectrometry.

Further characterization of glycine-containing microcystins from the McMurdo Dry Valleys of Antarctica [PDF]
, 2015 Microcystins are hepatotoxic cyclic peptides produced by several cyanobacterial genera worldwide. In 2008, our research group identified eight new glycine-containing microcystin congeners in two hydro-terrestrial mat samples from the McMurdo Dry Valleys ...
