A continuing effort in mass spectrometry is to optimize desorption/ionization processes in order to enhance analyte ion yields and reduce fragmentation. The effect of small carbohydrate and amino acid matrices on the yield of secondary ions from vitamin B 12 (cyanocobalamin) was examined using plasm

The negative ion mode of field desorption mass spectrometry is matrix dependent. "he matrix is used to facilitate the desolvation of ions at field strengths below the onset of field induced electron detachment. The role of the matrix in the desolvation mechanism for negative ions is briefly describe
The low-mass ions observed in both positive and negative plasma desorption mass spectrometry (PDMS) of the high explosives HMX, RDX, CL-20, NC, PETN and TNT are reported. Possible identities of the most abundant ions are suggested and their presence or absence in the different spectra is related to
