Reducing the Inner Filter Effect in Microplates by Increasing Absorbance? Linear Fluorescence in Highly Concentrated Fluorophore Solutions in the Presence of an Added Absorber

> 33.94). The IFE-corrected data are obtained by a single fluorescence measurement per sample without additional mathematical procedures. The method also does not require absorbance measurements, so it can be performed in non-transparent microplates with similar results. In addition, preliminary measurements indicate that the method is also suitable for measurements in standard cuvettes using a fluorimeter with a 90° angle setup.
