Quantitative detection of caffeine in beverages using flowing atmospheric-pressure afterglow (fapa) ionization high-resolution mass spectrometry imaging and performance evaluation of different thin-layer chromatography plates as sample substrates

HIGHLIGHTS

  • who: Maximilian Heide from the Department of and Biology, University of Siegen, Adolfu2011Reichweinu2011Str2, Siegen, Germany have published the research: Quantitative detection of caffeine in beverages using flowing atmospheric-pressure afterglow (FAPA) ionization high-resolution mass spectrometry imaging and performance evaluation of different thin-layer chromatography plates as sample substrates, in the Journal: (JOURNAL)
  • what: In this study it is demonstrated that a carefully selected surface for analyte spot sampling and co-deposited isotopically labeled standards both significantly improve the capabilities of flowing atmospheric-pressure afterglow (FAPA) highresolution (HR) MS for direct quantitative analysis.
