CUPD-1 is a copper anode donated by Phelps Dodge, El Paso, Texas, USA in January 1994.
Description
The material is in the form of sawings and contains approximately 99% copper, plus several elements at trace levels.
Intended use
CUPD-1 is suitable for the analysis of elements at trace levels. Examples of intended use are for quality control in the analysis of samples of a similar type, method development and arbitration.
Instructions for use
The assigned values pertain to the date when issued. CanmetMINING is not responsible for changes occurring after receipt by the user. CUPD-1 should be used “as is”, without pre-treatment. The contents of the bottle should be thoroughly mixed before taking samples.
Method of preparation
A magnetic separation was performed on the copper anode sawings. The resulting product was blended, degreased and bottled in 448 units, each containing 425 grams. This is the only size available.
