“…Energetic cluster stability is important in view of cluster assembled materials, and thermal cluster fragmentation as well as coalescence could easily be studied in gas suspension as well as chemical reaction with gases or other clusters. A second mobility analyzer and/or inertial impaction (Fernandez de la Mora et al, 2003) and/or mass spectroscopy would form a powerful combination for analysis of the product. …”

“…A fraction of the particles produced then obtain an elementary charge through electron attachment. Again the source of this charge is the wire itself, avoiding introduction of contaminants, as generally produced by aerosol chargers if conditions are not completely clean (Fernandez de la Mora et al, 2003). At wire temperatures below the limit of observable thermal emission, positively charged particles are formed.…”

“…1ms did not hinder atomic resolution in the separation of cluster sizes. For particles much smaller than the mean free path of the gas molecules it has been verified by Fernandez de la Mora et al (2003) that the inverse mobility is proportional to the square of the collision diameter of the atomic cluster, accounts for the diameter of the gas molecules. The relation above neglects polarization and recoil effects (Tammet, 1995) and is a rather crude approximation for particles in the ionic or atomic cluster size range.…”

A resistively heated metal wire is shown to be a source of charged atomic clusters consisting of only a few atoms. They are size classified with a differential mobility analyzer, and their relative abundance is determined as a function of size. Ag n K + clusters are obtained from wires containing silver with traces of potassium to provide the electric charge. First principles calculations reveal that the abundance observed can be fully explained by the energetic and chemical stability of the neutral cluster and K + attachment energy. K + attachment is a noninvasive way of charging, as the observed Ag n K + cluster properties are similar with respect to the pure Ag n clusters in terms of energetic and electronic stability and cluster structure. The equally-sized clusters are basically available for reactivity, coalescence and deposition studies, and the method is extendable to other materials.

“…The method was introduced by Schmidt-Ott et al (1980) and has been applied for the production of metallic particles for research purposes since then (e.g. Burtscher et al 1982;Schmidt-Ott et al 1997;Fernandez de la Mora et al 2003;Nasibulin et al 2005). The fact that a significant fraction of the particles formed is charged is of special interest because the aerosol is directly applicable for mobility classification, avoiding additional charging which usually introduces contaminants, as shown by de la Mora et al (2003).…”

This chapter describes the current and potential impact of ion mobility‐mass spectrometry (IM‐MS) for addressing the challenges of sample complexity, dynamic range, and throughput for metabolomics experiments. The four primary ion mobility techniques are described with regard to their defining analytical figures‐of‐merit. Tandem MS methods are reviewed, and novel tandem experiments made possible from multi stage activation in IM‐MS instrumentation are discussed in light of the additional information, such experiments provide for the analysis of metabolites.
