Oligosaccharide chains fluorescence‐labelled at their reducing end with 2‐aminopyridine were analysed by electrospray ionization mass spectrometry (ESIMS). Protonated molecules of complex type oligosaccharides were detectable at a level of 1 pmol. Fragmentation at the glycosidic bonds occurred in the ...
Quantitative analysis of biological membrane lipids at the low picomole level by nano-electrospray ionization tandem massspectrometry Nano-electrospray tandem mass spectrometry allows qualitative and quantitative analysis of complex membrane lipid mixtures at the subpicomole level. We hav... B Brugger,G ...
electrospray ionization mass spectrometry A method of mass spectrometry used to obtain the chemical analysis and weight of large molecules, especially proteins and peptides using a very small sample. The electrospray provides a charge on the molecules which are then injected into a mass spectrometer ...
The electrospray ionization source has been carefully optimized through a design of experiments that consisted of a two‐level fractional factorial design of resolution IV for the screening of adequate source conditions and of response surface designs for optimization of the main interactions between ...
Electrospray ionization in the study of sol‐gel processes: the polycondensation of Ti(O‐n‐Bu)4 in the presence of Si(OEt)4 The polycondensation of Ti(O-n-Bu)4 in presence of Si(OEt)4 (Et = C2H5, Bu = C4H9) has been studied by electrospray ionization of their mixture... S Crist...
The introduction of micro-electrospray[33]and later the nano-electrospray[34]have improved the ionization efficiency and thereby enabled the analysis of low sample volumes. Moreover, because nano-ESI is a softer ionization technique compared to traditional ESI, this ionization process will result in ...
There are two general approaches to elemental speciation: (1) integration of separation technology with element specific detection and (2) development and application of soft ionization sources. Electrospray ionization mass spectrometry (ESI-MS) has become a widely used technique in biological, ...

Pure cell population samples were analyzed by UHPLC–electrospray ionization mass spectrometry (LC–ESI–MS) to investigate the premise that VMN glycogen metabolism affects Gln, Glu, and Asp utilization in astrocyte and nerve cell compartments. The amino acid creatine (CR) has a critical role in ...
Electrospray ionization-mass spectrometry (ESI-MS) generates ions upon application of an electric potential to a flowing liquid, causing the liquid to get charged and then sprayed.
