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%.

NDELA经waters Atlantis T3色谱柱(150mm×2.1mm， 3μm)分离后在多反应监测模式下进行串联质谱定性及定量分析，以d8-NDELA为内标定量NDELA的方法定量限为50μg/kg；在50~250μg/kg的3个添加水平范围内的平均回收率为89.1%~98.2%，日内精密度均小于9%，日间精密度均小于11%。
