TM95-03 Graphite Furnace Atomic Absorption Spectrophotometry to replace Atomic Absorption Spectrometric, Chelation-extraction for the determination of molybdenum in water

Effective November 1, 1994, the National Water Quality Laboratory (NWQL) will be replacing the Atomic Absorption Spectrometric, Chelation-extraction method for the determination of molybdenum in water with a Graphite Furnace Atomic Absorption Spectrophotometry (GF-AAS) method. All molybdenum data released by the NWQL after November 1, 1994, will be determined by the provisionally approved GF-AAS method. Full U.S. Geological Survey (USGS) approval of this method will be pursued with an Open-file Report within 6 to 12 months.
