BL-2a Certificate of Analysis
Certified Reference Material: Uranium Ore
Printable version of the certificate (PDF, 272.83 kb)
BL-2a is intended as a replacement for reference ore BL-2, the supply of which is being depleted. BL-2a is a sample of ore that was typical of the property of Eldorado Nuclear Limited in Beaverlodge, Saskatchewan, and consists of pitchblende in reddish-brown mylonitized oligoclase saturated with dusty hematite.
The recommended value for uranium is the mean of single determinations, for each of 25 bottles of each reference material, performed at CANMET by the volumetric-umpire method.

A certificate of analysis will be issued with each order of BL-2a. A copy of CANMET Report 82-6E, "BL-2a and BL-4a: Certified uranium reference ores", will be forwarded, free of charge, on request to the Coordinator, CCRMP.
