As the total mass flow rate of mobile phase entering the flame-based detector changes (e.g., as a result of density programming in the separation), the mass flow rate of combustion gases to the detector are altered in proportion to the amount of mobile phase entering the detector. As a result, flame stability and sensitivity of the detector can be maintained by the methods and apparatus of the present disclosure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Modulated flame gas flow rates in flame-based detectors","description":"Methods and apparatus for the modulation of flame gas stoichiometry to a flame-based detector for use in chromatographic separations are presented.
