Stainless Steel

Increment division scoops are specialized stainless-steel tools designed for the precise, manual collection of material, typically for environmental soil samples or metal concentrates. They are crucial in Incremental Sampling Methodology (ISM) for reducing variability, ensuring that collected samples represent the total volume’s particle size and composition by taking numerous, consistent increments.

Design for Accuracy: Scoops are chosen based on the maximum particle size to prevent bias (e.g., minimum of three times the diameter of the largest particle). Square tools are preferred to avoid particle size bias (whereas rounded scoops might introduce it).

ISO Standards: Manual increment division often adheres to standards like ISO 12743/ISO 13543, which define specific scoop sizes (e.g., #0 to #20) for varied particle sizes ranging from: ≤ 0.25mm to ≤ 22.4mm.

Function: They are used to collect a portion of the material, which is often combined with other increments to create a larger, representative sample (gross sample).

Capacity: The tool must be able to reach the bottom of the sample depth and is generally selected to collect a targeted mass, often 20–60 grams per increment, depending on the material.

These tools ensure that the division (reducing sample mass without altering particle size) is done systematically, often using a “fixed-rate” approach to maintain the integrity of the sample.

Often used for Copper, Lead, Zinc & Nickel Concentrates as per AS 2862.2 (ISO 12743) concentrate sampling standard.
