,对应最小可探测吸收达到1.35×10⁻¹⁰ cm⁻¹。针对氨气分子易吸附于气室、管路内壁等诱发的响应延迟问题,采用的7.8 mL小腔体减小了分子滞留面积,关键管路与谐振腔内壁的硅烷钝化涂层降低了吸附,使系统平均响应时间缩短至196 s。本文为低浓度氨气的高精度、快速检测提供了可靠的解决方案。
To enhance the sensitivity and response speed of ammonia detection using laser absorption spectroscopy, optical feedback cavity-enhanced absorption spectroscopy (OF-CEAS) was employed. The characteristic absorption line of ammonia near 6 612.7 cm⁻¹ (1 512 nm) was selected as the target transition. A V-shaped optical resonant cavity composed of three high-reflectivity mirrors was constructed, with a single-arm length of 20 cm. The ring-down time of the empty cavity was measured to be 48.12 μs, corresponding to a finesse of approximately 100 000 and an equivalent absorption path length of 14.4 km. System stability was significantly improved through precise control of temperature and gas pressure. The optical setup was housed in a temperature-controlled chamber with a stability of ±0.005 °C. In addition, a self-developed high-precision pressure control system maintained the intracavity pressure at (30 000±1.5) Pa. Under these conditions, a detection limit as low as 12 parts per trillion (ppt) was achieved at an integration time of 168 s, corresponding to a minimum detectable absorption coefficient of 1.35×10⁻¹⁰ cm⁻¹. To mitigate response delays caused by adsorption of ammonia molecules on the inner surfaces of the gas cell and pipelines, a miniaturized cavity with a volume of 7.8 mL was implemented to reduce molecular residence. Furthermore, silane passivation coatings were applied to critical pipeline sections and the inner cavity surface to suppress adsorption effects, resulting in a reduction of the average system response time to 196 s.
