Journal ArticleDOI
Dioxin analysis by gas chromatography-Fourier transform ion cyclotron resonance mass spectrometry (GC-FTICRMS).
TL;DR: The feasibility of utilizing a gas chromatograph-tandem quadrupole-Fourier transform ion cyclotron resonance mass spectrometer for screening of CDDs/CDFs, HDDs/HDFs and related compounds was investigated by analyzing an extract from vegetation exposed to fall-out from an industrial fire.
Journal ArticleDOI
Absorption of the green fluorescent protein chromophore anion in the gas phase studied by a combination of FTICR mass spectrometry with laser-induced photodissociation spectroscopy
Konstantin Chingin,Roman M. Balabin,Vladimir Frankevich,Konstantin Barylyuk,Robert J. Nieckarz,Pavel Sagulenko,Renato Zenobi +6 more
TL;DR: In this paper, the intrinsic absorption of green fluorescent protein chromophore anion (HBDI − ) was probed by photo-induced dissociation (action) spectroscopy using discrete lines of a continuous-wave (CW) laser source.
Journal ArticleDOI
Native Biomolecules in the Gas Phase? The Case of Green Fluorescent Protein
TL;DR: Green fluorescent protein was ionized by native electrospray ionization and trapped for many seconds in high vacuum, allowing fluorescence emission to be measured as a probe of its biological function, to answer the question whether GFP exists in the native form in the gas phase or not.
Journal ArticleDOI
Infrared multiple photon dissociation (IRMPD) spectroscopy of oxazine dyes
TL;DR: The structural information obtained here in the gas phase pertaining to these important fluorophores is anticipated to provide further insight into their associated intrinsic fluorescent properties in solution.
Journal ArticleDOI
Optical properties of protonated Rhodamine 19 isomers in solution and in the gas phase
Konstantin Chingin,Roman M. Balabin,Vladimir Frankevich,Huanwen Chen,Konstantin Barylyuk,Robert J. Nieckarz,Alexey Fedorov,Renato Zenobi +7 more
TL;DR: The o-R19H(+) was found to have the largest Stokes shift in the gas phase (around 10 nm), suggesting that an intramolecular relaxation operates in the excited electronic state for this isomer.
