The T900 is fluorescence lifetime software dedicated
entirely for use with the TCC900 card. This software
enables lifetime data acquisition, data fitting, data
manipulation and presentation. The data acquisition
parameters can be set for Time Range (between 2.5ns and
50ms), STOP conditions (peak counts, time, manual), number
of channels (512, 1024, 2048, 4096), CFD parameters, shift
delay, forward or reverse mode of operation.
The T900 has all the excellent
fluorescence lifetime analysis features associated with
our F900 software. For comprehensive fluorescence lifetime
analysis the T900 uses non-linear least squares
reconvolution analysis procedures based on tried and
tested Marquardt Levenberg search procedures. As in the
F900 the Chi-squared goodness-of-fit test is utilised to
test for the best fit. Fitting of up to four exponential
decay-times, with full reconvolution analysis of up to
4096 channels of data, and optional iterative time shift
for precise fitting over decay curve, including rising
edge are all features of the T900 software.
Measurement modes for the T900 software are as follows:
• Signal rate
• Manual lifetime measurement
• Multiple lifetime measurement
• Time resolved excitation spectra
• Time resolved emission spectra
• Fluorescence anisotropy
• Temperature controlled lifetime measurements
• Sample temperature monitoring
The following analysis features are available in the T900
software
• Full data reconvolution using a non-linear least square
fitting routein – exponential fit or tail fit
• 1-4 independent exponential decay times, fixed or as
free fit parameters
• Shift parameters, fixed or as free fit parameters
• Background fit, fixed or as free fit parameters
• Chi-squared goodness-of-fit test
• Weighted residuals, Durbin Watson parameters
• Autocorrelation function
• Anisotropy calculation
• Time resolved spectra
Comprehensive data import and export facilities are also
provided to ensure compatibility with many other popular
analysis programs. |
