An Automated Approach to Luminescence Lifetime and Intensity Titrations

Journal of Fluorescence Aims and scope Submit manuscript

Abstract

An apparatus is described for the automated collection of luminescence emission decay curves over a wide range of analyte concentrations. The decay curves allow for determination of the excited-state lifetime or calculated steady-state intensity of a luminophore as a function of the analyte concentration. The data presented here demonstrate the use of the apparatus for pH titrations.
