FAST GC ANALYSIS AND ACCURATE MASS MEASUREMENT OF POPs BY USING A GAS CHROMATOGRAPH – HIGR RESOLUTION TIME-OF-FLIGHT MASS SPECTROMETER

摘要：

The fast GC techniques for persistent organic pollutants (POPs) analysis by using electron ionization (EI) and negative ion chemical ionization (NICI), have been investigated with a gas chromatograph – high resolution time-of-flight mass spectrometer (GC-HRTOFMS). As the result, POPs could be analyzed in only seven minutes under the fast GC conditions. To make effective use of a HRTOFMS, high-resolution mass chromatogram techniques were used. High sensitivity, repeatability and linearity on calibration curve were obtained under the fast GC and HRTOFMS conditions in EI mode and NICI mode. Especially in NICI mode, POPs standard sample of 0.03pg/mL could be detected clearly. By using a GC-HRTOFMS, high-sensitivity measurement and high-speed data acquisition could be compatible.
