Miniature cavity for in situ millimeter wave gas sensing: N2O and CH3OH detection
Sensors and Actuators B: Chemical(2018)
摘要
•A new millimeter wave spectrometer has a cavity 200 times smaller than conventional laboratory versions (nominally 12cm3).•Measurements of performance metrics are presented for various cavity configurations along with two gas detections.•The instrument opens new opportunities for in situ gas sensing.
