X-Ray Small Angle Scattering Analyzer principle is the use of a slit and a mirror, the X-Ray and the condenser for the polarization, the irradiation on the object, the small-angle scattering, the probe for receiving scattered X-Ray, the use of data obtained values, and determining the size of the physical characteristics of the atomic structure and density.
· Detailed principle
According to the structural characteristics of each substance has, scattering angles are different, the X-Ray irradiation on the material, small angle scattering, replaced with a digital signal their information, then this signal will become a reality material characteristics, structure and density information.
Without breaking the sample to be analyzed. Real-time measurements, the instantaneous change of the sensitive part of the sample such as immediate access to relevant data.
Recently used in various fields of nanotechnology genome (protein), a semiconductor material, a polymer material and environmental materials, etc., and continue to create new substances. SAXS is these substances at the molecular level structure (1nm ~ 10nm) to the atomic level structure (0.2nm ~ 1nm) measurements evaluated very unique X-Ray structural evaluation equipment.
From the sample is less than the nano-particle can grasp the size, shape, and orientation distribution of the internal structure and other information, which is widely used in the field of nanotechnology, polymers, fibers, catalysts, biological material and the bio-industry and the like.
For example, in the cosmetics industry in order to know the degree of dissolution of the particles, then to the solution, the distance between the nanoparticles, the relevant information can be obtained, but also to measure the size and density of the nanoparticles, and is applied using a plasma of nanoparticles production enterprise.
In addition, also on nano-powders and nano-composites, nano-size heterogeneity, quality, nano-sized particles of the powder substance Bender, pore size, Bulk shape, orientation, distribution and biological engineering (proteins, viruses, DNA ) detailed structure of the field, the detailed structure of a single dispersion of small particles and a synthetic polymer for analysis.
