Abstract

A device for spectroscopy using charged analytes has an electron generator, which sends electrons through membrane into a charging chamber. The thermal strain of the membrane may be lowered significantly if a material is selected for the membrane which contains at least one component from the group of oxides, nitrides, and carbides with at least one of the elements B, Al, C, Si, and Ti or polysilicon.
