Upper Great Lakes Connecting Channels interlaboratory performance evaluation study, QM-4 : major ions in surface water : final report / by W.A. Horn, R. Szawiola, D. Takeuchi and P.D. Leishman.: En13-5/87-64E-PDF

"This report describes the results from the fourth interlaboratory performance evaluation study, QM-4, which consisted of the analysis of 23 major ions and nutrients in surface water. Results were received from ten out of 13 participating laboratories (seven Canadian, three U.S,). Ten of the parameters were evaluated for bias by Youden's ranking technique and results which deviated significantly from the median were flagged. The rest of the parameters were evaluated for outliers by the Grubbs and Dixon tests. The interlaboratory comparability of major ion data was satisfactory for most of the parameters. Included in this report is a summary of each laboratory's performance"--Abstract, page ii.
