The characteristics of
Data import and display
DIFFRAC. SAXS can display a peacekeeping two-dimensional SAXS data, as well as Nanography figure.support的数据格式有brml、raw、ascii（拥有不同单位的两列数据格式xy 和三列数据格式xye）、gfrm和tiff。
Data preprocessing
DIFFRAC. SAXS can directly read scattering signal of nanostructures.
Carbon is the first step, the use of glass as a benchmark, or based on the primary beam intensity ratio, to determine the transmittance of the sample.Then, through the optimization of the algorithm will get the one-dimensional two-dimensional data integral data for further evaluation.
With DIFFRAC. WIZARD set up data measurement model, DIFFRAC. SAXS can automatically through rate calculation and the background correction, without user intervention.
SAXS curve unique way of display and analysis method
Traditionally, SAXS curve shows that for a particular axis curve of scale, in order to quickly check in the form of chart data quality, and to evaluate the parameters of the intuitive, such as Guinier, Porod and Kratky graph.DIFFRAC. SAXS allowed by name easily select all graph type.Radius of gyration (Rg), zero point scattering intensity, scattering Porod invariant and specific surface area and other related parameters can be completely, by step by step procedure automatically or interactively.
Based on the fitting of the model
DIFFRAC. SAXS by using geometry (sphere, cylinder, etc.) or a special polymer model (chain, Gaussian star, etc.) for the solution of the nano structure modeling directly, and can be carried out on a SAXS data nonlinear least-square fitting.It can also consider the effect of polydispersity and concentration, making sample characterization of more complete.Corresponding model parameters are determined by fitting the experimental curve of SAXS to.
Distribution function of distances
Distribution function of distance (PDDF) p ® represents the scattering particles in the distribution of the distance between any two points.PDDF is a function of the size and shape of the particles, through Fourier transform from scattering curve.
