Detection of bromochloro alkanes in indoor dust using a novel CP-Seeker data integration tool [PDF]

arXiv
Bromochloro alkanes (BCAs) have been manufactured for use as flame retardants for decades and preliminary environmental risk screening suggests they are likely to behave similarly to polychlorinated alkanes (PCAs), subclasses of which are restricted as Stockholm Convention Persistent Organic Pollutants (POPs).

Chemodiversity of dissolved organic matter in the Amazon Basin [PDF]

, 2016
Regions in the Amazon Basin have been associated with specific biogeochemical processes, but a detailed chemical classification of the abundant and ubiquitous dissolved organic matter (DOM), beyond specific indicator compounds and bulk measurements, has ...

Quantification of seminolipid by LC-ESI-MS/MS-multiple reaction monitoring: compensatory levels in Cgt mice[S]

Journal of Lipid Research, 2010
Seminolipid, also known as sulfogalactosylglycerolipid (SGG), plays important roles in male reproduction. Therefore, an accurate and sensitive method for SGG quantification in testes and sperm is needed.

High-resolution cryoEM structure determination of soluble proteins after soft-landing ESIBD [PDF]

arXiv
Soft-landing electrospray ion beam deposition (ESIBD), i.e. the chemically selective, intact deposition of large and complex molecules on surfaces in vacuum, is a well-established sample preparation method for scanning probe microscopy (SPM), where it facilitates the high-resolution imaging of large and complex molecules.

Identification of phosphatidylserylglutamate: a novel minor lipid in Escherichia coli

Journal of Lipid Research, 2009
Advances in mass spectrometry have facilitated the identification of novel lipid structures. In this work, we fractionated the lipids of Escherichia coli B and analyzed the fractions using negative-ion electrospray ionization mass spectrometry to reveal ...

Shaping electrospray plume with convergent sound beams

iScience
Summary: Electrospray ionization (ESI) is one of the mainstream ionization techniques for mass spectrometry (MS) nowadays. Here, we present a new variant of ESI-MS setup, in which an electrospray emitter points to the mass spectrometer’s orifice while ...

Mechanisms of Electrospray Ionization for Mass Spectrometry Analysis

, 2014
Electrospray ionization mass spectrometry (ESI-MS) is a choice method to accomplish the mass determination of large, non-volatile biomolecules including proteins, peptides, oligonucleotides, carbohydrates, polysaccharides and other compounds which are too large to be vaporized or too fragile to remain intact when other ionization methods are used.
