Pheromone measurement using secondary electrospray ionization and portable membrane inlet mass spectrometry

Key Points

• The study aims to develop a novel method for detecting insect pheromones using advanced mass spectrometry techniques.
• Utilized secondary electrospray ionization high-resolution mass spectrometry (SESI-HRMS) and portable membrane inlet mass spectrometry (MIMS).
• Conducted detection and monitoring of insect sex pheromones for the first time using these methods.
• Successfully detected various insect pheromones, indicating effectiveness of the SESI-HRMS and MIMS systems.
• Pheromone monitoring was accomplished in real-time, showcasing application potential in entomology.
