| Abstract: | A method was established to determine 1-Methyl-2-pyrrolidinone in water or gas sample by HPLC-tandem mass spectrometry.Water sample was injected directly into HPLC; l-Methyl-2-pyrrolidinone in gas sample was absorbed by active carbon and eluted by 30% acetonitrile/water. The detection limit is 0.012ng, linear range is 0.001～2mg/L. This method is sensitive,exclusive,fast,easy and with good recovery rate. |
