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.
ChlorAC™ Buffer from Pickering Laboratories is a highly purified Chromatographic Grade™ preservative. It is prepared from Monochloracetic acid and Potassium acetate to EPA specifications. ChlorAC™ is guaranteed to be free of co-eluting interferences for the analytes in EPA 531.1.
