Application of LAMMA in aerosol research

Laser microprobe mass analysis (LAMMA) as a tool for particle characterization: a study of coal fly ash

“…Overall, therefore, it is concluded that while LAMMA has considerable potential value for particle characterization, its widespread use in this mode must await further methodological developments and improvements in the technique. In these regards it is noted that direct sample collection on a transmission electron microscope grid have been reported (14,31). The largest single factor requiring improvement is the poor reproducibility of LAMMA analyses of individual particles and the difficulties with obtaining quantitative analytical information.…”

“…Furthermore, the time required for a single analysis is short, and sample preparation is relatively simple. The use of LAMMA in aerosol research has been demonstrated previously (5,(13)(14)(15)).…”

Laser microprobe mass analysis (LAMMA) and adsorption study of aliphatic alkylammonium ions and alkylamines on asbestos fibre surfaces

“…On the other hand, the mass resolution of 700-800 is only marginally adequate for inorganic analysis and for the characterization of fingerprint organic mass spectra. [16][17][18][19][20][21][22] For introduction of asbestos samples into the LAMMA instrument, a standard copper electron microscope grid, coated with a Formvar film, is brought into contact with the fibres. A number of them stick to the grid coating.…”

Interaction of laser radiation with solid materials and its significance to analytical spectrometry. A review

“…The microscope used in the LAMMA-500 instrument allows the analysis of particles down to 0.2 pm in diameter. 485 Several limitations of the technique for particulate analysis have been detailed,485 but despite these problems analytical data for individual particles and particle populations have been reported. The samples that have been studied have included airborne particulates,484 automobile exhaust fumes,485 calcium oxyanion and soot.…”
