PREP-SPL-17
Sample Preparation & Core Cutting
Riffle & Rotary Splitting, Blending & Compositing
Statistically sound sample reduction following Gy's sampling theory to ensure master pulp and duplicate aliquots are perfectly representative of the original deposit.
Detection Limits
Sub-sampling variance < 2.0%
Turnaround (TAT)
Standard: 24-48 Hours
Sample Requirement
Bulk crushed ore or pulp from 1kg to 100kg
Quality Framework
ISO/IEC 17025 Compliant
Analytical Overview & Methodology
Adhering to Pierre Gy’s particulate sampling theory, RVA Laboratories utilizes automated Rotary and Riffle Splitting Systems (PREP-SPL-17) to minimize fundamental sampling error.
