Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Registrierung von Teilchen oder Quanten bei einem spektroskopischen Analyseverfahren, bei dem den zum jeweiligen Meßverfahren gehörenden Einrichtungen (1) ein Detektor (4) nachgeordnet ist; um den Dynamikbereich zu erweitern, wird vorgeschlagen, zwischen dem Analvsator (1) und den Detektor (4) eine Ausblendung eines definierten Teiles der nachzuweisenden Teilchen oder Quanten dann vorzunehmen, wenn die Rate der den Detektor (4) erreichen­ den Teilchen oder Quanten einen maximal zulässigen Wert übersteigt. The invention relates to a method and a device for the registration of particles or quanta with a spectroscopic analysis method in which the for facilities (1) belonging to the respective measuring method Detector (4) is arranged downstream; to the dynamic range too expand, it is suggested between the anal (1) and the detector (4) hides a defined one Part of the particles or quantum to be detected when the rate of reaching the detector (4) the particles or quanta a maximum permissible value exceeds.
