Large temperature range and ease of use for a wide range of applications. There is a little low angle background as expected for this set of apertures, but no presence of crystalline peaks through the region scanned. Sample cooling and heating stage with liquid nitrogen cooling. The graph shows the background from ZBH #2 using a 1° divergence aperture (with no divergence Søller slit) and a 0.15° receiving aperture with the diffracted beam monochromator. Also, nanoparticle materials can collect in the polishing marks on the ZBH surface resulting in a change in the ZBH background. If the ZBH is scratched or marred, then there will no longer be zero diffraction background as diffraction peaks will arise from defects in the quartz.
The ZBH is prone to certain types of damage.
It shows the general region exposed to X-rays in the most common usage: a 1° divergence aperture with 2θ > 5°. Sample holder Sample surface Recommendation: - Set divergence slit to «variable. The dark region is where dislocations have been produced in the quartz by the X-rays. Fulfilling an important role in X-ray diffraction experiments, sample stages position the specimen in the centre of the instrument, increase the degrees of freedom of diffraction space exploration and present new specimens or additional measurement spots to the beam. The ZBH crystal is mounted in an aluminum frame. The only background produced by the ZBH is that due to the choice of the divergence aperture. For example, a metallic sample holder would produce diffraction peaks from the polycrystalline metal, and a glass slide would produce an amorphous background. Available Techniques: Powder Diffraction (Focusing Beam) Powder Diffraction (Parallel. It consists of a single crystal of quartz that is cut and polished in an orientation such that it produces no diffraction peaks. Capillary Attachment for Air- Sensitive Samples BioLogic Model SP-50 Single Channel Potentiostatand Coin Cell Holder for Simultaneous Electrochemical Characterization Numerous Sample Holders: Low Background, Zero Background, Airtight, etc. This image shows a zero background holder (ZBH). In Rigaku MiniFlex 6G for the small amount of samples they have zero background sample holders which can take samples from miligram size.
