Chromatography Standards
Pickering Laboratories Inc ChlorAC™ Buffer, 250 mL
Chromatographic Grade™ for Preservation of Aqueous Carbamate Samples. Trace analysis of Carbamate insecticide residues in drinking water is a mandated requirement in the U.S. Since several of the common Carbamates—Carbaryl, Oxamyl, Hydroxycarbofuran—are labile in water due to oxidation or hydrolysis, the samples and standards must be preserved in order to obtain valid results.
