For dynamic fluorescence measurements, two different approaches are te
sted: a classical photon counting approach, and an analogical approach
. After a description of the apparatus, on analysis of delay turves im
plying a neu, parametrization of the fluorescence decoy is described.
It provider a useful way to determine the simplest model which must be
retained to account for a fluorescence delay turves in terms of numbe
r of defined exponential decays. Very easy to use, this MSF is a usefu
l apparatus to account for the steady-state and dynamic fluorescence o
f microscopic samples.
