The analysis of amines by gas chromatograph ;mass spectrometry (GC–MS) using electron ionization (EI) has always been a challenge

The authors continue their discussion of the role of the analysis of fragment ions in the interpretation of an analyte's mass spectrum.

The authors discuss the use of electron ionization to determine a compound's structure.

American Society for Mass Spectrometry (ASMS) board member O. David Sparkman reviews the past year and summarizes the latest updates in mass spectrometry.
