CANMET-TPO-1 is a mixture of iron sulphide concentrate and tailings from the Clarabelle Mill that was originally prepared as a custom certified reference material for Inco Limited, Copper Cliff, Ontario, Canada in 1998. The raw material was dried at 60°C for 30 hours, crushed, sieved, and blended to obtain a minus 150 micron (100 mesh) product. The yield was 86%. The material comes in glass bottles containing 25-30g each. This is the only size available. Each bottle was sealed under nitrogen in a laminated aluminum foil-mylar pouch to prevent oxidation. TPO-1 is suitable for the analysis of elements at major, minor and trace levels. Examples of intended use are for quality control in the analysis of samples of a similar type, method development, arbitration and the calibration of equipment.
