ChronosDFD for lifetime measurements in complex decays in less than 1 second
ChronosDFD is fully-automated through Vinci, a user-friendly, Windows-based software package.
Key features of ChronosDFD include:
· Flexible instrument configuration with a variety of light sources (laser diodes, LEDs and Ti:Sapphire laser)
· A compact footprint and short optical path length for maximum sensitivity and efficient light coupling into the sample
· Second to picosecond lifetime measurement capabilities
· Full automation of instrument components including: cuvette holder, polarizers, shutters, filterwheel, monochromators and stirrers
·PC-controlled integration of temperature path,
titrator, stopped-flow apparatus and pressure pump
· Upgradable to a full steady-state instrument
·T-format and parallel beam optical design
for fast and precise polarization measurements
· Powered by Vinci-Multidimensional
Fluorescence Spectroscopy
Key characteristics of data acquisition via Frequency-domain:
· Fluorescence lifetime is calculated from two measureable parameters: phase angle and modulation
· Is a faster and less artifact-prone
· Allows one step measurements of anisotropy decays (rotational correlation times)
· Is better at resolving short lifetime contributions
· Is the method of choice for lifetime-based sensing and real-time measurements because of high sampling rates in the millisecond time scale
