Electron ionization tandem mass spectra of some 3-cyano-4-substituted phenyl-6-phenyl-2(1H)-pyridones
(John Wiley & Sons Ltd, Chichester, 2006)
Characterization and quantitative analysis of surfactants in textile wastewater by liquid chromatography/quadrupole-time-of-flight mass spectrometry
(Wiley, Hoboken, 2008)
A method based on the application of ultra-performance liquid chromatography (UPLC) coupled to hybrid quadrupole-time-of-flight mass spectrometry (QqTOF-MS) with an electrospray (ESI) interface has been developed for the ...
Study on the formation of an amoxicillin adduct with methanol using electrospray ion trap tandem mass spectrometry
(Wiley, Hoboken, 2008)
The possibility of using the protonated methanol-adduct of antimicrobial amoxicillin for its identification and quantification at residue levels has been investigated, since it is impossible to completely suppress the ...
Mass spectrometric study of some 4-pyrimidine carboxylic acids
(Wiley, Hoboken, 2002)
Mass spectrometry has been applied in order to study the main fragmentation routes of some 4-pyrimidene carboxylic acids. Differences in fragmentation were caused by the nature of the substituent in position 2 of the ...
Ionization energies of hypervalent Li2F, Li2Cl and Na2Cl molecules obtained by surface ionization electron impact neutralization mass spectrometry
(John Wiley & Sons Ltd, W Sussex, 2003)
Ionization energies of hypervalent Li2F, Li2Cl and Na2Cl molecules detected by surface ionization electron impact neutralization mass spectrometry are reported. The ionization energies were 3.78 +/- 0.2 eV for Li2F, 4.93 ...
