Definitions
- the transfer process also heats the molecule very strongly (excitation of rotation, vibration and electronic degrees of freedom).
- the molecule In the gas phase, the molecule has no efficient way to dissipate this excess energy (lack of coupling to a warm bath).
- molecular bonds can break or denaturation can occur.
- Spectroscopic analysis is also hampered by the high level of excitation. The gentle transfer of large molecules into the gas phase is of technical importance, for example as the first step in a mass spectrometric analysis.
- the object of the invention is also to provide devices for implementing such a method.
- the object of the invention also consists in the description of novel application possibilities for charged or unloaded cluster fragments which have been generated with the improved cluster fragmentation method.
- FIG. 7 shows the positive and negative mass spectra of the cations or anions in the cluster fragmentation according to the invention. on a gold surface.
- the selected reactive system consists of a cluster of polar SO 2 molecules and alkali atoms on the collision surface.
- the reaction in the cluster consists of the spontaneous release of the alkali valence electron onto an S0 2 molecule, mediated by the polar environment.
- Alkaline cations and SO anions are formed, which come to rest on cluster fragments due to the cluster fragmentation and are spatially separated from one another.
- the mass scale (abscissa) is plotted in units of S0 2 masses. The ordinate represents the measured ion number or ion intensity (arbitrary units).
- the cluster jet emerging from the nozzle opening strikes the target 72 of the cluster fragmentation device, which furthermore includes the adsorber feed devices 73.
- the target 72 is at earth potential and is continuously coated with adsorbates by the adsorbate supply devices 73, for example in the form of an evaporation furnace, during the operation of the ion engine.
- Clusters of polar carrier molecules and adsorbates of alkali metal atoms, for example cesium, are preferred.
- the positive and negative cluster fragments which arise in the course of the collision of the clusters with the adsorbate-covered target 72 are spatially separated with the aid of the extraction grids 74 and deflected in the desired direction by means of magnetic and / or electrical steering devices 75.
- a cluster beam system according to the invention can be equipped with a device for setting the electrical potential of the interface in order to set a certain potential for formation of the cluster fragments.
