Additionally, the fine wire may be coupled to a mounting post. In an implementation, a process for fabricating the corona ionization source assembly that employs the techniques of the present disclosure includes forming a wire core, forming a wire coating that surrounds the wire core, forming a mask layer on at least a portion of the wire coating, etching the wire coating, and removing the mask layer from the wire coating."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for a coated corona ionization source","description":"A corona ionization source assembly and fabrication methods are described that include a fine wire including a wire core including a first material, and a wire coating including a second material, whe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9837257","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.
