LUMINESCENCE LIFETIME BASED ANALYTE SENSING INSTRUMENTS AND CALIBRATION TECHNIQUE

摘要

A method of calibrating a luminescence lifetime sensing instrument 20 and of interrogating a target-analyte long-decay luminescence probe 120 includes measuring and reporting luminescence lifetime of the probe 120 employing excitation radiation filtered to remove emission radiation, or a starting time tstart delayed by a predetermined decay delay time, or delayed by a predetermined growth delay time, or an ending time comprising the time at which luminescence intensity has decayed or risen a predetermined percentage.
