摘要
采用高场非对称波形离子迁移谱技术,建立了快速识别香水种类的检测方法。在大气压条件下,以63Ni作为电离源,纯净空气作为载气,同时在正、负离子模式下进行检测。对检测条件进行优化,进样温度设为20℃,进样气和载气流量分别为0.1 L/min和1.4 L/min。在优化的条件下可以同时进行六种香水的快速分类和识别,重复性的相对标准偏差RSD≤6%。方法适用于香水等易挥发样品种类的快速识别。
A method of distinguishing different brands of perfumes by microchip-based high-field asymmetric ion mobility spectrometry (FAIMS) was established. In this method, 63 Ni was utilized as an ionizing source and pure air as a cartier gas. Both positive and negative ion detection at atmosphere could be achieved at the same time. By optimizing sample introduction temperature at 20℃, sample gas at a flow rate of 0.1 L/min and carrier gas at a flow rate of 1.4 L/min, the CV spectra of six brands of perfume were characterized. Unique features for each perfume were extracted for recognition. The relative standard deviation (RSD) of this method was lower than 6%. Compared with other instruments, this method has advantages in its rapid identification of perfumes and other volatile chemicals with hassle-free sample introduction process. Moreover, this work demonstrates the great capability of microchip-based FAIMS technology in the applications for rapid analysis and identification of volatile samples.
