Full Calibration Curve — Spiked Binder Standards
Spiked binders are prepared in high‑purity cellulose, each containing the element of interest at the following approximate concentrations: ~1, 5, 10, 25, 50, 100, 250, 500, 1000, and 2000 ppm.  Each single‑element binder set contains 2.0 grams of material, providing ample quantity for method development, repeatability checks, and long‑term calibration maintenance. 
 
Multi‑element combinations are available upon request, allowing you to tailor calibration curves to your specific matrix, application, or regulatory requirements.
