General description

N-Nitrosodimethylamine is a potent carcinogen, which can be formed in conditions of wastewater disinfection process, via the reaction between monochloramine and organic nitrogen-containing precursors.

Application

N-Nitrosodimethylamine may be used as an analytical reference standard for the quantification of the analyte in aqueous samples using different chromatography techniques.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

A sensitive procedure, microwave-assisted extraction (MAE) coupled dispersive micro solid-phase extraction (D-μ-SPE), was developed to extract N-nitrosodimethylamine (NDMA) and other six volatile N-nitrosamines (NAms) from meat products. Parameters affecting the efficiency of MAE and D-μ-SPE were systematically investigated. For MAE
