Fully Automated Sample Preparation System for Preparing and Analysing Samples for NDMA in Potable Water Using GC-QQQ:

The formation of N-Nitrosodimethylamine (NDMA), in treated sewage and environmental waters has been known for around 40 years.

NDMA is formed as a disinfection byproduct during chloramination of wastewaters and drinking waters and has been classified as “probably carcinogenic to humans” by both the International Agency for Research on Cancer (IARC) and the US Environmental Protection Agency (USEPA).

Presented in this application note is a fully automated sample preparation solution incorporating the solid phase extraction, to enrich NDMA from water samples. Large volume injection (LVI) is also automated to a GC-QQQ.
