SWD-PEAKFIT Software $595
For Windows 3.1, Windows 95 and Windows NT

• Find and separate overlapping peaks that out-dated and inaccurate numerical integration methods miss with PeakFit's state-of-the-art nonlinear curve fitting techniques.

• Save hours with PeakFit's fully automated peak finding and fitting routines. PeakFit has three different procedures to easily, accurately, and consistently quantify normal and hidden peaks.

• Stay in complete control by using PeakFit's fully graphical interface to override the automation at any time.

• Accurately process noisy data with PeakFit's highly advanced data smoothing and manipulation techniques.

• Analyze up to 100 peaks of any form by using any combination of PeakFit's 82 built-in nonlinear equations (18 specific to spectroscopy and 8 for chromatography). PeakFit also allows you to use up to 15 User Defined Functions.

• Easily find and subtract your baseline with PeakFit's constant zero second derivative baseline fitting routine.

• Remove instrument-induced data smearing with PeakFit's revolutionary deconvolution techniques.

• Utilize the full power of Windows 95 and NT with PeakFit's 32-bit code and Windows 95 interface. PeakFit is also fully capable on Windows 3.1.

With PeakFit, your accuracy will increase, and you'll find and fit your peaks faster than ever before. Don't rely on the inaccurate results of numerical integration techniques. PeakFit far surpasses any other peak analysis package made!

For Spectroscopy . . .
PeakFit lets you accurately detect, separate and quantify hidden peaks that standard instrumentation misses. PeakFit includes 18 different nonlinear spectral application line shapes, including the Gaussian, the Lorentzian, and the Voigt. As a product of the curve fitting process, PeakFit reports amplitude (intensity), area, center and width data for each peak. Overall area is determined by integrating the peak equations in the entire model. Also, PeakFit can deconvolve your spectral instrument response so that you can analyze your data without the smearing that your instrument introduces.

For Chromatography . . .
PeakFit includes 8 different built-in equations for asymmetric peaks typically found in chromatography data including the Exponentially-Modified Gaussian, the Haarhoff-Van der Linde, the NLC, the Giddings and even a Half-Gaussian Modified Gaussian, an experimental model similar to the EMG, but used to describe intra-column originated asymmetry. The peak area is computed directly as a parameter within each of these functions, ensuring accuracy and enabling computation of confidence limits. PeakFit reports column efficiency, resolution, first moment (center of mass), second moment, center (mode), as well as peak width at base and half maximum, and asymmetry at base and 10% of maximum. PeakFit can also deconvolve your chromatographic detector response, allowing you to analyze your data without the smearing that your instrument introduces.PeakFit supports AIA data file input.

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