What this note covers
Standard gold assay (PAAU02): LDL 0.010 ppm, precision from 12% at 0.1 ppm to <2% above 10 ppm, UDL 350 ppm at 72 samples/hour
Enhanced 4-cycle service (PAAU04) and 8-cycle service (PAAU08): improved LDL and precision at lower gold grades, at reduced throughput
Upper detection limit options up to 10,000 ppm via PAAU02H and PAAU02HH services
Background elements (uranium, thorium, barium) and interfering elements (bromine, erbium) — how each affects gold precision and detection limits
Moist sample measurement capability up to approximately 30% moisture, with indicative impacts on gold precision
