摘要
本文利用顶空固相微萃取-气相色谱质谱法(HS-SPME-GC/MS)对火场残留物样品中的生物柴油进行分析鉴定研究。通过SPME条件的优化、筛选实验和GC/MS分析条件的设立,建立了生物柴油的顶空固相微萃取-气相色谱质谱(HS-SPME-GC/MS)定性分析鉴定方法,其中SPME优化条件为微萃取头:100μm PDMS(红);加热温度:70℃;加热时间:50 min。实验结果表明该方法是一种简便高效、灵敏准确,分离分析效果好,抗干扰能力强的分析鉴定火场残留物样品中生物柴油的方法。
In this paper,the headspace-SPME-gas chromatography/mass spectrometry(HS-SPME-GC/MS)was used to analyze and identify biodiesel in fire residue samples.Through the optimization of SPME conditions,screening experiments and the establishment of GC/MS analysis conditions,a solid phase microextraction gas chromatography/mass spectrometry(SPME-GC/MS)qualitative method for the identification of biodiesel was established.The optimum SPME conditions are including that SPME is 100μmDMS(red),heating temperature is 70℃and heating time is 50 min.The experimental results show that the method is simple,efficient,sensitive and accurate,with good separation and analysis effect and strong anti-interference ability.
