Interlaboratory quality control study no. 5 : chromium, iron, molybdenum and vanadium / R.W. Wales and D.J. McGirr. : En36-508/26E-PDF

"Samples containing known amounts of chromium, iron, molybdenum and vanadium were distributed to thirteen laboratories to be analyzed by the laboratories' usual methods. The majority of laboratories determined the metals by atomic absorption; in addition, iron was determined colorimetrically for comparison. Only a few participants were able to analyze all four metals, and in the case of molybdenum and vanadium the small number of results received made it difficult to come to firm conclusions about the reliability of the method. The precision for chromium was better than in a previous study. The results obtained for iron by atomic absorption with solvent extraction were good, while the colorimetric method was intermediate in precision and sensitivity between solvent extraction and direct aspiration using atomic absorption"--Summary, page v.
