Qualitative and quantitative analyses were carried out for the analyte under the multiple reaction monitoring mode after the chromatographic separation on a Waters Atlantis T3 column (150 mm×2.1 mm, 3 μm). The quantitation was performed with deuterated N-nitrosodiethanolamine as internal standard. The limit of quantitation for N-nitrosodiethanolamine was 50 μg/kg. The mean recoveries were 89.1%-98.2% at the spiked levels of 50-250 μg/kg, with the intra-day precision less than 9% and the inter-day precision less than 11%.
