Advanced Nitrosamines Testing
At McCampbell Analytical Inc. (MAI), we’re proud to announce the launch of EEA Agilent 521.1 for the analysis of nitrosamines in drinking water. We boast a reliable quantitation down to 2 ng/L and a robust sample preparation with high recovery rates (>85%). As regulatory agencies tighten limits on these potent carcinogens, our lab is equipped with state-of-the-art GC-MS/MS instrumentation to ensure compliance and protect public health. EEA Agilent 521.1 is the latest approved revision of EPA 521. We have submitted our application for accreditation and anticipate approval by the end of 2025.
Why EEA Agilent 521.1?
Nitrosamines, particularly NDMA (N-Nitrosodimethylamine), NDEA (N-Nitrosodiethylamine), and other EPA-listed compounds, pose significant risks even at trace levels. These compounds can be naturally present in the water source or introduced during treatment processes such as the chlorination or chloramination. Many countries and regions have established regulations or guidelines for nitrosamines in drinking water. In California, notification levels and response levels have been established for NDMA, NDEA, and N-Nitrosodi-n-propylamine (NDPA).
