The results of these measurements are then automatically recorded in a PeakFit-generated report, or they can be shown graphically. The sophisticated array of baseline types lets you integrate only the significant portion of the bands in your data. With 82 nonlinear peak models to choose from, you’re almost guaranteed to find the best equation for your data. PeakFit gives the electrophoresis user the ability to quickly and easily separate, locate and measure up to 100 peaks (bands), even if they overlap.

PeakFit can even deconvolve your spectral instrument response so that you can analyze your data without the smearing that your instrument introduces. Overall area is determined by integrating the peak equations in the entire model. As a product of the curve fitting process, PeakFit reports amplitude (intensity), area, center and width data for each peak.

PeakFit includes 18 different nonlinear spectral application line shapes, including the Gaussian, the Lorentzian, and the Voigt, and even a Gaussian plus Compton Edge model for fitting Gamma Ray peaks. PeakFit lets you accurately detect, separate and quantify hidden peaks that standard instrumentation would miss.

The Fitting Functions and Features for PeakFit by Systat Software are shown below: Only PeakFit offers so many different methods of data manipulation. And, PeakFit even has a digital data enhancer, which helps to analyze your sparse data. AI Experts throughout the smoothing options and other parts of the program automatically help you to set many adjustments.

PeakFit also includes an automated FFT method as well as Gaussian convolution, the Savitzky-Golay method and the Loess algorithm for smoothing. This smoothing technique allows for superb noise reduction while maintaining the integrity of the original data stream. With PeakFit’s visual FFT filter, you can inspect your data stream in the Fourier domain and zero higher frequency points - and see your results immediately in the time-domain. PeakFit Offers Sophisticated Data Manipulation. PeakFit’s graphical placement options handle even the most complex peaks as smoothly as Gaussians. Each placed function has “anchors” that adjust even the most highly complex functions, automatically changing that function’s specific numeric parameters. If PeakFit’s auto-placement features fail on extremely complicated or noisy data, you can place and fit peaks graphically with only a few mouse clicks.
