If the net weight corresponds to an amount greater than the standard, the sample may be analyzed for the appropriate element and the result reported as the substance. note: Refer to Chemical Sampling Information for “alpha-Alumina” when sampling workplaces that have aluminum oxide exposures (welding, etc.). current elemental analysis method: Atomic Absorption Spectroscopy; AAS method reference: OSHA Analytical Method (OSHA ID-121) method classification: Fully Validated alternate analytical method: Samples are prepared as described in OSHA ID-121 and are analyzed by Inductively Coupled Argon Plasma; ICP/AES or ICP/MS. note: When analysis of aluminum metal is requested, an elemental analysis is performed and reported as aluminum metal. The analytical method does not distinguish between dust and fume; or between aluminum metal and other acid soluble or partially acid soluble aluminum compounds. Alternative Sampling/Analytical Method: sampling media: Mixed Cellulose Ester Filter (MCEF) 0.8 µm preceded by 10 mm Nylon Cyclone maximum volume: 816 Liters minimum volume: 408 Liters flow rate: 1.7 L/min current elemental analysis method: Atomic Absorption Spectroscopy; AAS method reference: OSHA Analytical Method (OSHA ID-121) method classification: Fully Validated alternate analytical method: Samples are prepared as described in OSHA ID-121 and are analyzed by Inductively Coupled Argon Plasma; ICP/AES or ICP/MS. note: When analysis of aluminum metal is requested, an elemental analysis is performed and reported as aluminum metal. The analytical method does not distinguish between dust and fume; or between aluminum metal and other acid soluble or partially acid soluble aluminum compounds.
