99.99% Silicon Blank for Handheld XRF Soils Mode Verification

The 99.99% Silicon Blank Sample for Handheld XRF Analysis is a simple, practical QC tool for users running handheld XRF in soils, environmental, geochemical, or screening applications. Because silicon is a clean, low-background matrix for many handheld XRF workflows, this prepared blank sample can be used to verify that your analyzer is not showing unexpected elemental carryover, contamination, or false positive results.

Each sample is prepared in a 32 mm XRF sample cup with 4 micron Prolene film, making it ready to use right out of the box. This format is convenient for routine instrument checks, operator training, and troubleshooting when you want a consistent blank sample on hand.

This sample is especially useful for handheld XRF users running soils mode who want a quick way to check system performance before testing unknowns or after measuring high-concentration samples.
