What this note covers
Detection limits for PhotonAssay™ standard (2-cycle) and precision (4-cycle and 8-cycle) gold services, tested on reagent-blank materials
Instrument precision across a range of gold grades, from low-grade CRMs (sub-100 ppb) through to high-grade reference materials (46+ ppm)
Impact of background elements — uranium, thorium and barium — on PhotonAssay™ gold measurement precision and detection limits
How sampling error affects total measurement uncertainty, and when running additional aliquots outperforms switching to a higher-cycle service
Real-world performance data from a Ravenswood Gold Mine case study using 26 low-grade plant samples
