A microwave resonator flame ionization detector assembly includes a microwave resonator disposed proximate a flame to evaluate an ion concentration in a flame effluent. A resonant frequency of the microwave resonator is detected, and a reflection coefficient of the resonator is used to determine an electric permittivity of a material in which the resonator is immersed. The electric permittivity depends on an ion concentration proximal to the resonator, and the ion concentration is related to the concentration of hydrocarbons present in the flame. 一种微波谐振器式火焰离子化检测器组件，包括：微波谐振器，所述谐振器邻近火焰设置以评估火焰流出物中的离子浓度。微波谐振器的谐振频率被检测并且谐振器的反射系数被使用以确定谐振器所浸入于的材料的电容率。电容率取决于谐振器附近的离子浓度，离子浓度与火焰中存在的碳氢化合物浓度有关。
