Custom Analytical Packages (XRF)

SRC’s Advanced Microanalysis Centre™ provides one of the simplest, most accurate and economical methods for multi-element analysis using an x-ray fluorescence (XRF) spectrometer.

Key Features

  • Fast, non-destructive analytical method suitable for solid, liquid and powdered samples
  • Elements from carbon to uranium can be measured with a detection range of 1 to 50 ppm


XRF Sample Preparation

  • Loose Powder (LP):
    • Finely ground material is homogenized and placed in a polypropylene cup fitted with a 6 μm thick mylar window and analyzed in a He atmosphere. Typical MDL: 100 ppm
  • Pressed Pellet (PP):
    • Finely ground material is mixed with a binding agent and homogenized. The mixture is hydraulically pressed into a pellet 40 mm in diameter and 5 mm thick. Pressed pellets are analyzed under vacuum. Typical MDL: 1 10 ppm.
  • Fused Bead (FB):
    • Finely ground material is mixed with a lithium borate flux, melted together at 1100°C and quenched to a glass bead in a 40 mm diameter Pt mold. Fused glass beads are analyzed under vacuum. Typical MDL: 10 50 ppm.
  • Aqueous Solutions:
    • Dissolved material is analyzed in polypropylene cups with a 6 μm mylar window under in a He atmosphere. Typical MDL: 10 100 ppm.

Analysis options for XRF include pre-made packages (following pages) or custom designed analytical routines. Minimum sample fees may apply.

We can develop custom analytical packages for your business with calibration standards derived from your samples for maximum compatibility between standards and unknowns. Contact us to learn more.
