Abstract
A sample (EC) is mounted on a sample carrier (PO). Vertically thereabove a common optical portion (5) receives a beam of primary ions derived from an ion source (S10) together with a beam of primary electrons derived from an electron source (S30). The secondary electrons and ions due to the sample (EC) being bombarded by said primary ions and electrons are retrieved by said common optical portion (5). The electrons are detected by electron detection means (D40). The secondary optical system (2) transmits the secondary ions to a mass spectrometer (SP20). This instrument is capable of providing ion and electron images of a single sample simultaneously.
