微型气相色谱(GC)系统可以在超小的包装中提供快速、定量的化学蒸气分析。我们描述了一种化学传感器技术的基础上共振纳米机电系统(NEMS)质量检测器,提供所需的速度,灵敏度,特异性和尺寸的微尺度GC范例。这样的NEMS传感器已经证明了对膦酸酯分析物的十亿分之一(ppb)浓度的检测。通过将NEMS检测的两个通道与超快GC前端相结合,在5秒的时间窗口内对13种化学物质进行了色谱分析。
Miniaturized gas chromatography (GC) systems can provide fast, quantitative analysis of chemical vapors in an ultrasmall package. We describe a chemical sensor technology based on resonant nanoelectromechanical systems (NEMS) mass detectors that provides the speed, sensitivity, specificity, and size required by the microscale GC paradigm. Such NEMS sensors have demonstrated detection of subparts per billion (ppb) concentrations of a phosphonate analyte. By combining two channels of NEMS detection with an ultrafast GC front-end, chromatographic analysis of 13 chemicals was performed within a 5 s time window.
