  • Abstract
    We present a transportable dual-modulation Faraday rotation spectrometer with minor isotope (15NO) detection sensitivity of 0.35 ppbv·Hz-12, corresponding to 1.4x the shot-noise limit. NO isotope line-switching is implemented for quasi-simultaneous time-multiplexed isotope measurements.
