DART（真实的时间直接分析）是一种创新技术，通过简单地将复杂的固体样品放置在DART离子源和质谱仪之间，在大气压和地电位下分析复杂的固体样品。分析物通过中性亚稳物质的离子枪电离。第一个例子的应用DART的分析风味和香料原料在真实的，复杂的应用程序在这里报道。一个显着的高潜力的技术证明。DART应用于半定量分析香料原料沉积在嗅条。在最佳情况下，达到约100 pg的检测限。DART还允许评估香味在织物和头发等表面上的沉积和释放。最后，DART允许在不到30分钟的时间内筛选12个口香糖样品中可能存在的口味清新化合物。
DART (Direct Analysis in Real Time) is an innovative technology to analyze complex solid samples at atmospheric pressure and ground potential by simply placing them between a DART ion source and a mass spectrometer. The analytes are ionized by a gun of neutral metastable species. The first examples of the application of DART to the analysis of flavor and fragrance raw materials in real, complex applications are reported here. A remarkably high potential of the technique is demonstrated. DART was applied to semi-quantitative analyses of perfumery raw materials deposited on smelling strips. In optimal cases, limits of detection around 100 pg were achieved. DART also allowed the assessment of the deposition and release of fragrance on surfaces such as fabric and hair. Finally, DART permitted the screening of twelve chewing gum samples for the possible presence of taste-refreshing compounds in less than 30 min. Copyright (C) 2007 John Wiley & Sons, Ltd.
