应用高分辨质谱实时分析方法研究口呼气和鼻呼气有机组分的存在特征OA北大核心CSTPCD
Real-time Analysis of Organic Composition of Oral and Nasal Breath Air by High Resolution Mass Spectrometry
通过人体口呼或鼻呼均可采集呼气样本,但口腔和鼻腔环境会影响呼气组分,因此,探究口呼气和鼻呼气的成分,对理解口腔和鼻腔环境对呼气组分的影响以及选择合适的采样方式均具有重要意义.本研究采用二次电喷雾电离高分辨质谱技术(Secondary electrospray ionization-high resolution mass spectrometry,SESI-HRMS)实时在线分析呼气样品,建立了人体呼气中常见挥发性有机物(Volatile org…查看全部>>
Human exhaled breath has great application prospects,e.g.,monitoring pharmacokinetics,disease diagnosis,due to its advantages such as non-invasive and high-frequency sampling.Breath samples can be collected from the oral and nasal cavity.However,the oral and nasal environment affect the chemical composition of breath sample.Therefore,the investigation on the chemical composition of mouth-exhaled breath and nose-exhaled breath is crucial for selection of appr…查看全部>>
