Qualitative and quantitative analyte analysis is omnipresent: from quality control in food, pharmaceutical, biotechnology industries, to new molecular syntheses, detection of explosives and drugs, as well as natural compound mixture analysis, such as crude ...

While frequently employed as an experimental technique, the mechanistic picture surrounding the gas-phase dissociation of peptides carrying multiple positive charges during electron capture and electron transfer dissociation tandem mass spectrometry remain ...

Atmospheric pressure photoionization (APPI) is a technique of choice for ionization of non-polar molecules in mass spectrometry (MS). Reported APPI-based studies tend to focus on a selected compound class, which may contain a variety of functional groups. ...

We describe a mass spectra recalibration method, which enables analysis of petroleum samples with Orbitrap FTMS. In this method, the mass calibration function is estimated on the basis of mass-to-charge ratios and abundances of internal calibrants without ...

Fourier transform mass spectrometry (FTMS) enables comprehensive analysis of complex molecular mixtures. Given the broad intensity ranges of components in the mass spectra, it is imperative to accurately determine a noise threshold level above which peak a ...

The synthesis of topologically complex structures, such as links and knots, is one of the current challenges in supramolecular chemistry. The so-called Solomon link consists of two doubly interlocked rings. Despite being a rather simple link from a topolog ...

RATIONALE: Previously described methods for producing absorption mode Fourier transform ion cyclotron resonance (FTICR) mass spectra have all relied on the phase correction function being quadratic. This assumption has been found to be invalid for some ins ...

Because of the high complexity of petroleomic-type samples, there is a need for efficient ways of visualizing and interpreting the resulting data in mass spectrometry-based petroleomics. Over the years, several graphing approaches have become widespread, y ...

This tutorial review describes the principles and practices of electron capture and transfer dissociation (ECD/ETD or ExD) mass spectrometry (MS) employed for peptide and protein structure analysis. ExD MS relies on interactions between gas phase peptide o ...

Electron capture and electron transfer dissociation (ECD/ETD) tandem mass spectrometry (MS/MS) are commonly employed techniques for biomolecular analysis. The ECD/ETD process predominately cleaves N-C-alpha peptide backbone bonds, leading to primary sequen ...

A versatile and experimentally facile procedure for the synthesis of borophosphonate cages of the general formula [tBuPO3BR′]4 is described. The method involves heating of tert-butylphosphonic acid with a boronic acid in toluene to give borophosphonates in ...

A facile and flexible method for the synthesis of a new AAA–DDD triple hydrogen-bonding motif is described. Polytopic supramolecular building blocks with precisely oriented AAA and DDD groups are thus accessible in few steps. These building blocks were use ...

It is possible to control the geometry and the composition of metallasupramolecular assemblies via the aspect ratio of their ligands. This point is demonstrated for a series of iron- and palladium-based coordination cages. Functionalized clathrochelate com ...

Electron capture dissociation (ECD) tandem mass spectrometry (MS/MS) is a powerful analytical tool for peptide and protein structure analysis. The product ion abundance (PIA) distribution in ECD MS/MS is known to vary as a function of electron irradiation ...

Mass spectrometry techniques employing electron capture and electron transfer dissociation represent powerful approaches for the analysis of biological samples. Despite routine employment in analytical fields, the underlying physical processes dictating pe ...

The performance of the high-field Orbitrap Fourier transform mass spectrometer (FTMS) is evaluated in the context of petroleum sample analysis. Pertinent characteristics including resolving power, mass accuracy, and spectral dynamic range are tested with r ...
