DW-XRD-27mini Desktop XRD
It is designed for commercial process and quality control. It is a concentration of advanced technology of XRD production, with multi-function and miniaturization. It can do qualitative analysis, quantitative analysis and crystal structure analysis on metal and nonmetal sample, especially for catalyst, titanium dioxide, cement and pharmacy industries.
Equipment Performance
1. High frequency high voltage X-ray generator has greater stability, so it guarantees the repeatability of the data.
2. Goniometer θs, θd arm adopts servo motor drive and optical encoder control technology, so the goniometer rotates more smoothly, the diffraction angle measuring is more accurate and the linearity is better. Within the diffraction angle range, the diffraction linearity <0.02.
3. The scattered ray protective device is safer and more reliable. When it is measuring samples, the protective door will be auto-locked to avoid the radiation to the people.
4. DW-XRD-27mini XRD adopts the most advanced metal ceramic X-ray tube, it has long service life (3000 hours); the automatic 6-sample changer can improve the sample measuring speed and convenient for the operator.
5. The compact structure can installed onto the platform without special laboratory environment. It is easy for operation and maintenance.
Application
DW-XRD-27mini XRD can do qualitative and quantitative analysis on polycrystalline material. During qualitative analysis, it will indentify the unknown structure by comparing the measuring data with known phase data base. During quantitative analysis, it can describe the characteristics of the solid mixture, so that to confirm relative content of the crystalline compounds or un-crystallized phase.
