China Desktop Xrd Is An Economical Choice

    In previous work and graduate school management X-ray diffraction labs, we knew there were many factors to consider when adding or replacing X-ray diffraction (XRD) in your lab. The [u]China benchtop xrd[/u] may be a compact and economical alternative to floor-standing. Determining which factors are key requirements to meet your needs will help you choose the right desktop for your situation.


    1. Determine the acceptable performance level of the application
      A key aspect of the performance to consider when purchasing a Chinese desktop xrd is resolution. Compact XRDs typically have a smaller radius at which the X-ray tube and detector are adjacent to the sample being tested, which affects resolution. The China China desktop xrd market offers a range of resolution capabilities, so it's important to determine which ones meet your needs.


    If your work is routine, there are fewer phases in the sample, or if you focus primarily on nanomaterials, then resolution may not be important to get enough quality data to meet your analytical goals. However, if you are studying complex mixtures or looking for the presence of small polymorphs or trace phases, the solution should be an important factor in your evaluation process. The ability to distinguish small peaks is critical to indicate an unexpected or unwanted phase, especially for patterns with many peaks.

    Another measure of performance is the linearity of the goniometer. The highly linear goniometer provides accurate peak position over the entire 2θ range of the goniometer. This is important if you are making critical calculations from Chinese-Chinese benchtop xrd data, such as lattice parameters or the unit cell size of the cracking catalyst. Linearity is determined using line position criteria such as NIST 640e - Silica. For good peak position accuracy, the 2θ linearity should be within /- 0.02 degrees 2θ.

    If you need to analyze drugs or other organic materials, clay or mesoporous materials, the low angle performance in your standard list should be high. Low angle reflection will be the key to correcting phase identification and requires accurate, non-standard quantitative analysis. Low angle performance can be demonstrated using appropriate low angle standards (eg, mountain silver acid). Excellent low-angle performance will show clearly identifiable peaks with the correct intensity ratio as low as 1 degree 2θ.
