AccuTOF™ GC, Mass Spectrometry (MS), MS Application Notes |

In this MSTips, we introduce the results of analysis of the aroma components of spearmint essential oil by gas chromatography-time-of-flight mass spectrometry (GC-TOFMS). Since essential oils are natural materials extracted from flowers, leaves, and seeds of plants, they are expected to contain substances not registered in the NIST database. Therefore, we used JMS-T2000GC and msFineAnalysis AI, which are capable of AI structural analysis, for the analysis.

AccuTOF™ GC, Mass Spectrometry (MS), MS Application Notes |

The detection sensitivity of the FI method largely depends on the wire configured in the emitter and the form of the whiskers created on the wire surface. We have developed a new emitter with the wire and conditions for creating whiskers optimized for the FI method in order to improve detection sensitivity. The effectiveness of this emitter is reported below by comparison with conventional emitters.
