Diffraction, abbreviation XRD) it is the two methods that material composition analysis is carried out using X ray different qualities.Work as beam of x-rays
When being radiated at material surface, it may occur that the scattering of X ray and absorbing phenomenon.Under certain condition, the coherent scattering of X ray, which is formed, spreads out
Penetrate striped, different diffraction fringe represents the different structures of matter, therefore XRD survey meters be mainly used in analyzing material thing phase and
Crystal parameter, it is widely used in the fields such as material, metallurgy, cement, mineral products.The energy that X ray carries is inhaled by material internal electron
Receive, produce electron transition and discharge fluorescent X-ray.The energy and quantity and material element composition and content phase of fluorescent X-ray
Close, so XRF survey meter is mainly used in obtaining element composition and the quantitative analysis of testing sample, in mineral exploration, survey
Well, Marine Environmental Geology investigation etc. are used widely.
At present, in an analytical instrument, two kinds of analytic functions of XRF and XRD is provided simultaneously with and are had been carried out.The structure of use
It is broadly divided into two kinds：
(1) combining structure pattern, exactly XRF and XRD main functional modules are assembled, radiographic source, light path and spy
It is independent to survey most of device, can ensure analytical effect to the full extent.Chinese patent CN200880007232 proposes a kind of
The integrated mode of X-ray tube is shared, XRD analysis use the method based on angular instrument.Chinese patent CN201010569788 then gives
A kind of combining structure of shared X-ray tube is gone out, XRD uses energy dispersion type measuring method, and detector uses one-dimensional energy type；
Above-mentioned two patent is all to use simple sample, i.e. XRD and XRF share sample.
(2) single structure pattern, due to the minimizing of XRF, portable highly developed, and XRD portable research
Also it is confined to partial analysis instrument producer.Using single structure pattern, XRF points are mainly realized during XRD analysis
Analyse function.But because the two X ray demand to incidence is different, and during XRD analysis, the fluorescent effect of X ray
It is interference signal, XRD analysis effect can be reduced, therefore using XRF the and XRD compositive instruments of single structure pattern, it is main prominent
Analytic function go out or XRD.
In recent years, the minimizing of XRD analysis instrument, the portable emphasis for being designed to industry concern.Some are large-scale
XRD analysis apparatus manufacture is proposed Table top type, miniaturization XRD, but directly applies at the scene also fewer.Limit portable
The major obstacle that XRD is developed is that the weight, volume and the inherent of instrument performance index of instrument constrain.Although such as angular instrument so that
XRD analysis precision is high, measurement angle scope is big, but due to belonging to precision optical machinery rotating device, is not easy to work at the scene
