TCSPC Lifetime Flyer


TimeMaster™ 2000 comes with FelixGX software for instrumental control and includes new PowerFit-10 analytical software for fluorescence and phosphorescence lifetime analysis.

Through the new, powerful ASOC-10 USB interface FelixGX provides a full set of data acquisition protocols and controls the hardware for all system configurations and operating modes.

FelixGX Controls

  • Timing of digital detector delay gate
  • Monochromator
  • Motorized slits (optional)

FelixGX Acquisition Modes

FelixGX also provides several acquisition modes for fluorescence decay measurements:

  • Fluorescence Decay with user controlled integration time per point and user selectable linear, arithmetic or logarithmic timescale
  • Time-Resolved Emission scan with user control of integration time, time delay of detector gate, scan step size and number of emission spectra averaged.  
  • Time based scan with user control of integration time, time delay of detector gate and total time window.

PowerFit-10 Analytical Software

PowerFit-10 software (incorporated into FelixGX) provides powerful analytical package for decay data analysis. All modules include reconvolution algorithms, selection of data weighing (Poisson or analog), shift and offset parameters, statistical goodness-of-fit parameters (Chi-square, Durbin-Watson, Runs test, residuals and autocorrelation), as well as standard deviations of fit parameters.

PowerFit-10 Modules

  • Multi-exponential (1 to 4 lifetimes) decay
  • Multi-file multi-exponential (1 to 4 lifetimes)
  • Global (1 to 4 lifetimes) analysis
  • Anisotropy decay (free rotor, restricted rotor and other models)
  • Stretched exponential
  • Micelle quenching kinetics (Infelta-Groetzel-Tachiya model)
  • Exponential Series Method (ESM) unconstrained lifetime distribution analysis (up to 200 exp terms)
  • Maximum Entropy Method (MEM) lifetime distribution analysis (up to 200 exp terms)
  • Time-Resolved Spectra (TRES)
  • Decay Associated Spectra (DAS)
