Lifetime determination of low sample concentrations: a new cuvette for highly accurate and sensitive fluorescence measurements.

A new cuvette was developed for spectrofluorometric measurements which increases the efficiency of recorded fluorescence emission by at least two-fold, decreasing, at the same time, the noise component of the record. It is suited for both steady-state and dynamic fluorescence measurements. Comparative data for both the classical and the novel cuvettes are presented here.
