M is calculated by electronics which use Rave(t) from a pulsed signal and reference channel output and a calibration curve which is validated by use of RJave(t2) from a pulsed interference and reference channel output. Signal, interference and reference sources are pulsed at a frequency which is sufficiently fast so that a given molecule of M or MJ will not pass in and out of the liquid sampling matrix within the pulsing frequency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"NDIR interference control in liquids","description":"NDIR is used to determine a concentration of a chosen molecule M in a liquid sample which contains one or more interfering molecules MJ which absorb radiation at the signal wavelength used in the NDIR","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9726601","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.
