Applications of laser microprobe mass spectrometry in organic analysis

Mass Spectrometry of Aerosols

“…Many reviews of this field have already been published. ,,− Therefore, a comprehensive overview is not our goal; instead our objective is to present an overview of the technique and how it is applied to aerosol research. First, LAMMS instrumentation is introduced illustrating the different possible configurations of commercial instruments as well as discussing common operating conditions.…”

Organic and inorganic analysis with laser microprobe mass spectrometry. Part I: Instrumentation and methodology

“…Finally, motorization of the sample positioners has been tried in order to achieve mapping [48]. Although successful applications are feasible (49)(50), automated analysis is hindered by the effect of the laser focus on the local power density, and, hence, the typical features of a spectrum (51).…”

Interpretation of Mass Spectra from Organic Compounds in Aerosol Time-of-Flight Mass Spectrometry

“…Previous work using laser microprobe mass analysis (LAMMA), the off-line forerunner to these real-time techniques, has elucidated some aspects of the ionization and fragmentation mechanisms observed using laser desorption/ionization. − However, to date there has been no investigation of the capability of RTSPMS techniques for analysis of the wide range of compounds known and expected to be present in atmospheric particles. The purpose of this study is to understand and identify potential characteristic ion peaks in the mass spectra of various relevant compounds and compound classes expected to be present in atmospheric particulate matter.…”
