DC-Arc Copper Analysis

Unmatched Accuracy and Convenience Bring DC-Arc Copper Analysis to a New Level of Confidence Never Before Achieved.

· CopperSpec makes two DC-Arc instrument calibration series with certified values. The High Purity Series ^TMconsists of eight (8) concentration levels: 0.1 ppm, 0.5 ppm, 1.0 ppm, 3.0 ppm, 5.0 ppm, 10.0 ppm, 20.0 ppm, 50.0 ppm for the following ten (10) analytes (plus zinc.) The ten analytes (Ag, As, Bi, Fe, Ni, Pb, Sb, Se, Sn, Te) are required for ASTM Grade I copper cathode certification. The LME Series consists of eight (8) standards at the same concentration levels as the High Purity Series ^TM. This series includes five (5) analytes plus gold. These additional analytes are required for LME Grade A copper cathode certification: Co, Cr, Mn, P, Si, +Au.

· Both calibration series are traceable to the Commission of the European Economic Communities: Community Bureau of Reference BCR Certified Reference Material 074 and 075 as well as the U.S. National Institute of Standards and Technology (NIST) Copper Benchmark series.

· Step-wise concentration increase from 0.10 ppm to 50.0 ppm provides for a complete calibration curve for each analyte.

· Standards are pickled and pre-cut to custom weights between 250 mg and 500 mg according to customer needs.

· Accurate pre-cut weights provide for very small error bars and relative standard deviations during calibration and daily use.

· Complete calibration curve coverage and accurate pre-cut weights combine to create calibration curves rivaling aqueous ICP analysis.
