Dynals software

Dynals v2.0 is a completely rewritten version of Dynals. The first version of Dynals released in 1996 has proved itself as the fastest, reliable and user-friendly software for Particle Size Distribution analysis in Photon Correlation Spectroscopy also known as (Quasi Elastic or Dynamic Light Scattering).
Dynals uses proprietary, NTSVD algorithm for solving the associated ill-posed mathematical problem.

Dynals v2.0 includes the old as well as new computational methods:

  • Particle Size Distribution analysis with reliable automatic or visually assisted choice of regularization level
  • Distribution Peak Analysis gives full information about individual peaks in the computed distribution
  • Robust, GLSA based multi-exponential analysis (up to four components) with automatic choice of initial conditions
  • Cumulant Analysis with variable number of cumulants

Dynals v2.0 includes many other new features that make in unique software for data analysis:

  • Simultaneous plot of experimental data, residuals, computed particle size distribution and its peak analysis as well as graphical representation of multi-exponential and cumulant analysis
  • Simultaneous analysis and overlapping presentation of results for several experimental data sets greatly simplifies comparison without using any external software
  • Simultaneous analysis and results presentation of experimental data by different processing methods provides additional confidence in the results
  • Export of results in text format or in one of popular image formats
  • Export of result into file or clipboard for easy import into documents, presentations and image handling software
  • External control interface allows running and controlling Dynals v2.0 from other applications

Dynals v2.0 support several types of input data formats:

  • Simple data format (*.dat)
  • Tagged Data Format (*.tdf)
  • Photocor Instruments data format (*.txt)
  • new: Brookhaven data format (*.dat)
  • new: ALV data format (*.asc)
