LC/MS spectrum

An extensive list that defines acronyms and abbreviations in the field of mass spectrometry was published in 2002 [6], A single analytical technique or a type of instrument is abbreviated without hyphens or slashes. However, it is customary to use hyphens for a description of an instrument whereas an abbreviation that describes the method uses slashes. For example, LC-MS is an instrument where a liquid chromatograph is coupled with a mass spectrometer, while LC/MS is the method of liquid chromatography/mass spectrometry. Thus, one uses an LC-MS instrument to obtain a LC/MS spectrum.

Determined on the basis of LC-MS spectrum (integration of diode array 200-400 nm traces) of isolated product. Not completed and obtained noncycbzed product in about 20% yield.
