The standard sample is intermittently introduced into the ionization chamber via a pulse valve (216). Thus, mixing of the sample to be measured and the standard sample can be prevented, while the timing according to which the standard sample is introduced can be appropriately controlled. It also becomes possible to acquire an accurate mass spectrum for each sample to be measured even in the case where a number of types of samples to be measured are introduced into the ionization chamber one after another over a short period of time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mass spectrometer","description":"The mass spectrometer (1) provides an ionization chamber (11) therein with: a probe (15) having a sample to be measured flow path (155) for spraying a sample to be measured; and a standard sample flow","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9741548","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.
