ASTM F 2405 Document Information:
Title
Standard Test Method for Trace Metallic Impurities in High Purity Copper by High-Mass-Resolution Glow Discharge Mass Spectrometer
ASTM International
Publication Date:
May 1, 2004
Scope:
This test method covers the concentrations of trace metallic
impurities in high purity (99.95 wt. %
pure, or purer, with respect to metallic trace impurities) electronic
grade copper.
This test method pertains to analysis by magnetic-sector glow
discharge mass spectrometer (GDMS).
This test method does not include all the information needed to
complete GDMS analyses.
Sophisticated computer-controlled laboratory equipment, skillfully
used by an experienced operator,
is required to achieve the required sensitivity. This test method does
cover the particular factors
(for example, specimen preparation, setting of relative sensitivity
factors, determination of
detection limits, and the like) known by the responsible technical
committee to effect the
reliability of high purity copper analyses.
This standard does not purport to address all of the safety concerns,
if any, associated with its
use. It is the responsibility of the user of this standard to
establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
