Ammonia desorption chemical ionization mass spectra (NH3-DCIMS) of phosphatidylsulfocholines, a mixture of a homologous series of phosphatidylsulfocholines (PSC) and a mixture of a PSC and a phosphatidylcholine (PC), were measured by a flash heating method involving introduction of 1/xg of the sampl

During the control of a multistep organic synthesis on a soluble polymer (PEG) by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry, a chemical reactivity was encountered when the matrix was acidic, for the samples where the amino moiety of the anchored compounds was protected as
The ammonia/desorption chemical ionization (DCI) mass spectra of nine cyclopentaoe iridoid glucosides were measured. The dependences of the intensities of different peaks on the structures and stereochemistries of the compounds investigated is discussed.
