International Butyltin Measurement Methods Intercomparison: Sample Preparation and Results of Analyses

摘要

A comparison of prevalent organotin measurement methods has been conducted on an international scale with a new tri-n-butyltin research material distributed to over 40 participating laboratories worldwide. A description of background research into the behavior and manipulation of low-concentration (ppm) aqueous organotin solutions, chromatographic production and packaging of the stable speciated butyltin research material in water, and quantitative results from the international methods intercomparison are reported here along with recommendations for future work.
