The invention provides a method and a measurement system for characterization of luminescence properties, the method comprises irradiating the luminescent material with a pulse of excitation light, providing a triggering signal correlated to the pulse of excitation light; detecting with a photodetector such as a photomultiplier tube (PMT) a plurality of photons emitted from the luminescent material as result of the pulse of excitation light, the photodetector providing an output signal upon the event of detection of a photon; determining for each detected photon a photon arrival time and providing an output suitable for inputting to an analysing module wherein an output comprises zero, one, or more photon arrival time for each excitation, receiving said outputs in an analysing module; and determining in the analysing module, characteristics properties of the luminescent material by performing a statistical analysis based on Bayesian inference.

System and method for time correlated multi-photon counting measurements

The present invention relates to a method, a measuring cell and a system for measuring very small heat changes in a sample. The system comprises a measuring cell for containing the sample during the measurement process, at least one electromagnetic radiation unit for radiating one or several samples with modulated monochromatic or polychromatic radiation inside said measuring cell . Said measuring cell comprises at least one acoustic transducer for generating a first output signal V(t) and at least one heat measuring device for generating a second output signal T(t). Both signals are connectable to a combining unit that generates an information signal by means of a reference signal f(t). Said information signal is connectable to a signal processing unit for determining at least one relevant reaction parameter as a function of the measured heat change.
