| titleOfInvention | High-sensitivity determination method for nitrosamine in water based on high-resolution mass spectrum |
| abstract | The invention discloses a high-sensitivity determination method of nitrosamine in water based on high-resolution mass spectrometry, which is characterized by comprising the following steps: the method comprises the following steps: after sample pretreatment, a water sample is separated by a chromatographic column, detected in a high-resolution mass spectrum full-scanning mode, and quantified by an internal standard method, wherein the sample pretreatment comprises solid-phase extraction enrichment and nitrogen-blowing quantitative concentration. The method has the detection Limit (LOD) of 0.05-0.5 ng/L and the quantitative Limit (LOQ) of 0.1-1.0 ng/L for different substances, which are far lower than the limit level of countries in the world at present, the linear range of 0.2-500 mug/L and the correlation coefficient (R) 2 ) Is 0.9943 to 0.9997. |
