Method 7029

Copper as Dust and Fumes

This method is used for the determination of copper as dust and fumes. The sample is collected on cellulose ester membrane filters, ashed in concentrated nitric acid @ 140 °C, followed by concentrated hydrochloric acid at 400 °C, and then analyzed by flame atomic absorption. The working range is 0.05 to 1.3 mg/m³ for a 100 L air sample. This is an elemental analysis, applicable to either dust or fumes, with an additional separation step to quantitate soluble copper dust (e.g., copper sulfate) in the presence of copper fume. Aliquots of samples can be analyzed separately for many additional metals. NOTE: This method combines and replaces P&CAM 173, S354, S186. Method 7300, plasma emission ( ICP-AES) is an alternate analytical technique.
