摘要

Laser desorption mass spectrometry (LDMS) is reviewed with focus on application to structural analysis of nonvolatile organic compounds. Models for the ionization-volatilization step are discussed with reference to solid-state vs. 'gas-phase' reactions. General characteristics of LDMS of organic compounds are discussed; for example, classes of compounds that generate M+ ions or (M+H)+ ions. Cationization reactions are considered; organic salts are discussed. Particular emphasis is placed on LDMS of high molecular weight compounds such as polysaccharides, polymers and vitamin B12 and its relatives. Problems of ion-molecule reactions complicating spectra are considered, particularly for transition metal coordination compounds. Other topics considered include quantitative analysis, microprobe applications and sample handling. (Author)
