Description générale

EPA 521 Nitrosamine Mix is a multi-component solution containing N-nitrosodimethylamine, N-nitrosodibutylamine, N-nitrosodi-n-propylamine, N-nitrosomethylethylamine, N-nitrosodiethylamine, 1-nitrosopyrrolidine, and 1-nitrosopiperidine as certified reference materials (CRMs). The raw materials and solvents used in the preparation of EPA Method 521 Nitrosamine Mix have been screened for identity and purity. The mixture is gravimetrically prepared and quantitatively analyzed by gas chromatography (GC).
US EPA 500 Series methods are analytical methods for identifying and quantifying organic contaminants such as volatile organic compounds (VOCs), pesticides, synthetic organic compounds (SOCs), and trihalomethane disinfection byproducts (THMs) in raw source water, finished drinking water, and drinking water at all stages of treatment.

Application

EPA 521 Nitrosamine Mix may be used as a CRM to quantify N-nitrosamine analytes in fast food products, meat-derived products, tertiary alkanolamine-based carbon dioxide (CO2) capture systems, environmental water samples, and drinking water and drinking water treatment plants(6) by analytical techniques.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Autres remarques

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
