Bulk Analysis

A non-destructive method suitable to analyze the elemental composition of the object’s surface.

Recommendation

  • For best results, the surface of the sample should be as flat as possible with a maximum diameter of 12 in and thickness of 3 ½ in. The ideal shape of specimen dimensions 1 1/8 in (diameter) and 3 ½ in (thickness).
  • The average turnaround time is two weeks per 10 samples.

Methodology

The sample’s surface is cleaned with ethanol. The sample is then placed into the XRF spectrometer sample chamber above the X-ray source window and measured under an air atmosphere. If possible, scans are obtained from different areas of the sample.

Results

Semi-quantitative analyses are obtained using Rigaku’s RPF-SQX (Rigaku Profile Fitting-Spectra Quant X) software combine with the FP (fundamental parameters) method. The LLD or LOD are determined by the software. The final report includes the content of Na, Mg, Al, Si, P, S, K, Ca, Ti, Mn, and Fe oxides in wt. percentages, and concentration of other elements in ppm.
