How to Monitor Samples for XRF

XRF is the X-ray fluorescence analysis test that analyzes all elements in the periodic table from beryllium to californium, in powder, solid and liquid form. An XRF spectrometer can monitor and analyze small to large concentrations of the elements without diluting the sample. The XRF method is used for both research and industrial processes. Sample preparation for XRF differs depending on whether the element is liquid, solid or a filter sample.

Things You'll Need

XRF analyer
Sample cup for XRF analyzer

Instructions

- 1
  Calibrate the XRF analyzer as instructed in the user manual. Obtain a sample cup specific to the XRF analyzer for liquid samples. You must use a liquid sample holder for measurement. The liquid phase for the sample is a direct way to conduct XRF analysis because no preparation is needed.
- 2
  Prepare the metal samples by creating solid disks using machining methods such as cutting, milling and polishing. To obtain the best results using the XRF analyzer, the metal samples should be formed into disks. For polishing, use a fine abrasive to produce a scratch-free surface on the metal and a mirrorlike surface for light elements. Polishing the metal is important for fluorescence intensity.
- 3
  Prepare solid particle samples contained in gas, air or water through the filter disk method. Draw the gas, air or water sample through a filter disk in a vacuum to filter out the particles. Place the sample in the sample cup for analysis in the XRF analyzer.
- 4
  Turn on the XRF analyzer. Place samples as instructed in the user manual. The XRF analyzer prints out the results.
