Semi-quantitative analysis of drilling mud

The Primini XRF spectrometer was used to analyze curious samples from a drilling application.

The sample was dried and ground in a mortar and pestle, loaded into a disposable sample cup with Prolene supporting film and analyzed as a loose powder on the Primini using the very simple EZ Scan semi-quantitative analysis routine.

From the analysis (Figure 1), it was determined that the deposits were likely contaminated with a zinc-rich anti-seize compound used on the threads of drilling pipes. A spectral chart (Figure 2) compares the contaminated drilling mud residue with a more typical drilling mud sample.

The Primini is a compact WDXRF system that fits well in space limited areas such as drilling platforms. With an analytical range from F - U it has proven itself useful for simple tests like this to more complex analysis situations.

Rigaku's Primini Biofuel is suitable for phosphorus analysis in biodiesel for EN14214 and ASTM D6751. It is optimized for sub-ppm detection limits of P, S and Cl and features easy operation without chemical treatment of the samples. Easy sample preparation and operation reduces the need for a highly skilled operator. A helium atmosphere is maintained in the spectroscopic chamber and sealing film separates the sample chamber from the spectroscopic chamber, protecting the X-ray tube and the spectrometer in the event of a spilled oil sample.
