All eight D-aldohexoses and aldohexoses derived from the non-reducing end of disaccharides were investigated by variable-wavelength infrared multiple-photon dissociation (IRMPD) as anions in the negative-ion mode. Spectroscopic evidence supports the

Differentiation of glucose-containing disaccharides by infrared multiple photon dissociation with a tunable CO2 laser and Fourier transform ion cyclotron resonance mass spectrometry

Autor: Sarah E. Stefan, John R. Eyler

Publikováno v: International Journal of Mass Spectrometry. 297:96-101

Lithiated glucose-containing disaccharides with various linkages and anomeric configurations, formed by electrospray ionization (ESI) and trapped in a Fourier transform ion cyclotron resonance (FTICR) mass spectrometer, were fragmented by infrared ra

Publikováno v: Analytical chemistry. 83(22)

Data mining algorithms have been used to analyze the infrared multiple photon dissociation (IRMPD) patterns of gas-phase lithiated disaccharide isomers irradiated with either a line-tunable CO(2) laser or a free electron laser (FEL). The IR fragmenta

Differentiation of methyl-glucopyranoside anomers by infrared multiple photon dissociation with a tunable CO(2) laser

Autor: Sarah E. Stefan, John R. Eyler

Publikováno v: Analytical chemistry. 81(3)

Fragmentation of lithium cation-attached alpha- and beta-O-methyl-glucopyranoside precursor ions, formed by electrospray ionization (ESI) and trapped in a Fourier transform ion cyclotron resonance (FTICR) mass spectrometer, was produced by infrared r
