High-precision resolution for multi-exponential fluorescence decay is obtained by
completely automated multifrequency phase fluorometry, using the harmonic content of the …

The basic theory of a frequency domain fluorometer has been known since the original work
of Gaviola (1)• With the introduction of multifrequency capabilities and the use of ultra high …

I. SUMMARY Phase-modulation fluorometry is the frequency-domain analogue of time-
resolved fluorescence spectroscopy. During the past three years we witnessed the …

We describe the construction and performance of a variable-frequency phase-modulation
fluorometer. This instrument, which provides modulation frequencies from 1 to 200 MHz, was …

A detailed description of the construction and performance of a variable frequency cross-
correlation phase fluorometer is reported. The phase fluorometer operates over the …

The analog electronics commonly found in frequency domain fluorometers are limited to
collecting only a single frequency at a time, and can be a source of systematic errors. We …

We measured fluorescence phase shift and modulation data for one-, two-and, three-
component mixtures of fluorophores at modulation frequencies ranging from 1 to 140 MHz …

A new fiber-optic-based fluorescence lifetime instrument is described which is useful for the
study of complex fluorescence decay kinetics. The new instrument consists of a …

Feddersen et al. use pulsed cross-correlation techniques to obtain time resolved information
of fluorescence decays employing frequency domain techniques. While the implementation …

The technical simplicity and speed of cross-correlation frequency domain fluorometry has
been compromised recently by the need to measure and analyse the phase and modulation …
