摘要：The ionization chamber comprises a non-radioactive ionization source (10), a reaction partial chamber, a feed for introducing an analyte to the reaction partial
chamber, and a line for removing the analyte. The ionization chamber comprises a non-
radioactive ionization source (10), a reaction partial chamber, a feed for introducing an analyte to the reaction partial chamber, and a line for removing the analyte. The positive pole of a beam potential is connected to an X-ray anode (13) in an evacuated partial chamber so that an X-ray beam produced in the anode hits a separating wall (15) which is impermeable to electrons but permeable to the electron beam produced in the anode. An electrode is arranged in the reaction partial chamber to produce photoelectrons in a conversion layer. Preferred Material: The separating wall is made of beryllium and has a thickness of 10-200 mu m, or is made of mica and has a thickness of 7-40 mu m.
