IMS-493

IMS-493 is a Crushed (<3mm) Gold Hosted Silicate Rock Chips reference material specifically designed for PAL1000™ technology, offering precise quality control for gold (Au) analysis. Compliant with ISO 33405:2024, this engineered material features dispersed gold within its mineralogical structure, ensuring homogeneity and stability for high-throughput PAL analysis workflows.

Key Features

• Certified Value (As-received PAL1000™, 500 g):
  • 1.62 g/t Au (±0.085 SD, 95% CI: 1.57–1.68 g/t).
• Method-Specific Validation:
  • Certified using results from 11 participating PAL1000™ laboratories, with assay masses between 420–500 g and AAS finish.
• Engineered Gold Distribution:
  • Manufactured from a patented engineered rock with dispersed gold embedded within the mineralogical structure to provide excellent homogeneity for PAL analysis.
• Packaging:
  • Supplied in 500 g labelled heat-sealed bags for direct analysis without further preparation or sub-sampling.
• Validity:
  • Certificate valid for 5 years from the certification date (7th July 2026).

Key Certified Values

Intended Use

• PAL1000™ QC: Validate instrument performance with as-received 500g samples (no preparation needed).
