Software
QuantaMaster™ 40 comes with FelixGX software for the control of the instrument and accessories, which also includes analytical functions for trace manipulation and spectral and kinetic 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:
- Monochromators
- Motorized slits
- Motorized polarizers
- Motorized sample holders
- Temperature control Peltier devices
- Gain control of PMT detector
- Switching from digital to analog mode
- External devices such as stopped flow
FelixGX Acquisition Modes
FelixGX provides several acquisition modes for spectral and kinetic measurements:
- Excitation and Emission spectral scans with user control of integration time, monochromator step, speed and wavelengths
- Timebased scan with user defined macro-time duration and integration time
- Timebased polarization with full control of motorized polarizers and automated measurement of G-factor and sample background for all polarizer orientations
- Simultaneous multidye measurements with pre-defined library of common fluorescence dyes or customer defined dyes
- Synchronous scan with excitation and emission monochromators scanning simultaneously with a fixed offset between the two
- Software switching between digital and analog detection and software PMT gain control in the analog mode
PowerFit-10 Analytical Software
PowerFit-10 software (incorporated into FelixGX) provides powerful analytical package for decay data analysis. Although primarily designed for fluorescence lifetime analysis, it’s also a very useful tool for studying chemical kinetics. All modules include user-selectable 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)
