[PDF] Ammonia Detection by use of Near-Infrared Diode ...

We describe a portable diode-laser-based sensor for NH(3) detection using vibrational overtone absorption spectroscopy at 1.53 mum. Use of fiber-coupled optical elements makes such a trace gas sensor rugged and easy to align. On-line data acquisition and processing requiring <30 s can be performed with a laptop PC running LabVIEW software. The gas sensor was used primarily for NH(3 ...

New sensors for ammonia gas detection | News | gasworld

Jun 08, 2020 · This means, long term performance in an environment around -20 ℃ will not be good for electrochemical sensor. At -20 degrees centigrade there is little water vapour in the air for the ammonia gas detector to operate. A current alternative is to use optical sensors for Ammonia gas detection based on infrared technology.

Near-infrared fiber-coupled off-axis cavity-enhanced ...

Jun 15, 2021 · A near-infrared ammonia (NH3) sensor system based on a novel fiber-coupled off-axis cavity-enhanced thermoelastic spectroscopy (OA-CETES) was demonstrated for the first time. A quartz tuning fork (QTF) with a high Q-factor of ~12000 was served as a detector and placed after a 6cm-long off-axis integrated cavity with a finesse of ~482. The proposed fiber-coupled scheme was adopted …

Open-path atmospheric ammonia sensor - Harvard University

ammonia sensor operating at 9.06µm for high sensitivity, high temporal resolution, ground-based measurements. Atmospheric ammonia (NH3) is a gas-phase precursor 5 to fine particulate matter, with implications for air quality and climate change. Cur-rently, NH3 sensing challenges have led to a lack of widespread in-situ measure-ments.

How to Detect Ammonia: 8 Steps (with Pictures) - wikiHow

29-04-2021 · Use an infrared (IR) sensor for long-term stability. IR sensors use infrared radiation to find the levels of ammonia in an area and can be purchased through online retailers. They do not need to be reset or calibrated as often and they do not degrade from large amounts of ammonia exposure, though they are large and need to be protected from changes in temperature. [6]

Abstract. Hyperspectral thermal infrared sounders enable us to grasp the global behavior of minor atmospheric constituents. Ammonia, which imparts large impacts on the atmospheric environment by reacting with other species, is one of them. In this work, we present an ammonia retrieval system that we developed for the Greenhouse Gases Observing Satellite (GOSAT) and the estimates of global ...
