The method includes irradiating a sample to acquire an initial energy spectrum. The energy spectrum is processed to identify a sum-peak that interferes with a characteristic fluoresced peak of an element of interest. A filter is positioned in the emitted radiation path to attenuate radiation that contributes to the identified sum-peak, and a filtered energy spectrum is acquired. In certain embodiments, the filtered energy spectrum is acquired only when a limit of detection (LOD) of an element of interest calculated from the initial energy spectrum does not satisfy a targeted objective."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Automated sum-peak suppression in an X-ray fluorescence analyzer","description":"A method of operating an x-ray fluorescence (XRF) analyzer to automatically suppress sum-peaks is disclosed.
