A first ionizer is operatively connected the housing to supply ions at the upstream end. A second ionizer is operatively connected to the housing to supply ions at the upstream end, wherein the first and second ionizers are both situated upstream of the drift zone relative to an ion flow path through the drift zone. An electric field generator is operatively connected to the housing to drive ions through the drift zone in a direction from the upstream end toward the downstream end. The second ionizer is a radioactive ionizer mounted to the housing at the upstream end positioned to direct irradiated ions into the housing."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ionization for tandem ion mobility spectrometry","description":"An ion-mobility spectrometer system includes a housing with an upstream end, a downstream end, and a drift region defined along a longitudinal axis through the housing between the upstream and downstr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11525803","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
