CORRECTION FOR OSMOTIC PRESSURE VARIATIONS IN CHEMO-OPTICAL SENSOR SPOTS |
| 摘要 |
The present invention relates to a method for optically determining the concentration of a gas, 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), wherein said dyes show different luminescence decay times so that the resultant phase angle is indicative for the concentration of a gas, characterized in that the detected luminescent amplitude of the reference dye at a first moment in time is utilized to correct for sensitivity changes after said moment. The present invention also relates to a corresponding method for quality assessment of the measurement of an optical sensor for determining the concentration of a gas. |

1. A method for optically determining the concentration of a gas, 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), wherein said dyes show different luminescence decay times so that the resultant phase angle is indicative for the concentration of a gas, characterized in that the detected luminescent amplitude of the reference dye at a first moment in time is utilized to correct for sensitivity changes after said moment. |
