Version 3.2 of the FluoFit multiexponential fluorescence decay fit software for PCs has been released by PicoQuant. The company says the new software provides better ASCII data import, support for the latest TimeHarp 200 data formats and for all previous 32-bit Windows platforms. It provides a graphics installer; registered users of previous versions receive a free update. Instrument response function and decay background and time shift are included at fit parameters; parameters and options can be adjusted manually. Graphical sliders can be used to adjust fit limits.
