SE-54 毛细管柱测精油和芳香萃取物残留苯

名称:毛细管柱

  固定液:5%苯基-95%二甲基聚硅氧烷

  型号:SE-54

  规格:30m*0.25mm*0.25um

  应用: 精油和芳香萃取物 残留苯含量的测定 气相色谱法

滕州市浩瀚色谱仪器技术服务有限公司，建立了测定精油和芳香萃取物中残留苯含量的方法,分别考察了静态顶空和直接进样两种进样方式、两种不同固定相的色谱柱、氢火焰离子化检测器（FID）和质谱检测器（MSD）两种检测器。实验得出结论：对于挥发性较大的样品采取直接进样的方式进行测定,不易挥发的样品采用顶空进样方式。实验结果表明,在1×10-6～2.5×10-5浓度范围内,采用不同的组合,残留苯含量均具有良好的线性关系。

Capillary column measurement of residual benzene in essential oils and aromatic extracts
Capillary column for measuring residual benzene of essential oil and aromatic extract Details:

Name: Capillary column

  Fixation solution: 5% phenyl-95% dimethyl polysiloxane

  Model: SE-54

  Specification: 30m*0.25mm*0.25um

  Application: Determination of residual benzene content in essential oils and aromatic extracts Gas chromatography

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. has established a method for determining the residual benzene content in essential oils and aromatic extracts. It has investigated static headspace and direct injection two injection methods, two different stationary phase columns, Two detectors are hydrogen flame ionization detector (FID) and mass spectrometry detector (MSD). The experiment draws a conclusion: for the more volatile samples, the direct sampling method is used for measurement, and the less volatile samples are sampled by headspace. The experimental results show that in the concentration range of 1×10-6～2.5×10-5, with different combinations, the residual benzene content has a good linear relationship.
