The method includes using at least two luminescent dyes, the first being in-sensitive to the concentration of a gas with respect to the luminescence response (reference dye) and the second being sensitive to the concentration of a gas with respect to the luminescence response (indicator dye) the dyes show different luminescence decay times so that the resultant phase angle is indicative for the concentration of a gas, wherein the detected luminescent amplitude of the reference dye at a first moment in time is utilized to correct for sensitivity changes after the first moment."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Correction for osmotic pressure variations in chemo-optical sensor spots","description":"The present invention relates to a method for optically determining the concentration of a gas.
