摘要
Pyridine in 15 mL aqueous sample was micro-extracted by using a head space sampling-solid phase microextration system of 75 μm CarboxenTM-Polydimethylsiloxane (CAR-PDMS) fiber.The extractants were measured by Gas Chromatography-Mass Spectrometry (GC-MS) with selected ion monitoring (SIM) mode and internal standard quantitative method.Under the optimum conditions of an extraction temperature of 58.0 ℃ for 40 min. Head space sampling-solid phase microextraction (HS-SPME),an organic solvent-free pre-processing method for water sample,can protect SPME coatings,especially for dirty samples.An MS detector has advantages in qualitative analysis and avoids the fake positive signal effect.Head space-solid phase microextraction is a convenient and sensitive method.
