本研究利用FAIMS（强场非对称波形离子迁移谱）芯片搭建的检测设备，成功实现了对白酒中DEHP （邻苯二甲酸二（2-乙基）己酯）和DINP（邻苯二甲酸二异壬酯）的检测。通过顶空进样装置，以空气为载气，将加热挥发的样品送入检测核心，得到相应的信号，并通过软件转化为对应的谱图。对比含有塑化剂的样品和纯净样品的谱图，可确定塑化剂在谱图上的位置。该设备对不同浓度样品检测结果显示，其精密度低于气相色谱-质谱联用仪，检测信号值与浓度成高度正相关。利用含塑化剂样品制作样机标尺，在软件中设置报警浓度，实现对白酒中塑化剂的快速检测。

The equipment based on FAIMS(field asymmetric waveform ion mobility spectrometry ) chip was established to detect DEHP and DINP in wine successfully. Sample was heated and evaporated into de-tect core with air as the carrier gas through headspace sampler ,and obtained the corresponding signals . They were transformed into the spectrum diagram by the software .The test results of phthalate esters in various concentration showed the precision was lower than GC-MS's and the signal value had a relationship with concentration of phthalate esters in direct proportion.
