SCUID - a Platform for In-Situ Dissolved Gas Measurement of N2O and NO
This work introduces SCUID (Submergible Carbon nanotube Underwater Instrument for dissolved gas Detection) to the oceanographic instrumentation community. SCUID is a small, low-power, real time dissolved gas sensor system that is deployed via the ship’s CTD, can ultimately be tuned to different gases of interest, and allows for high spatial resolution sampling.
The SCUID sensor marries two mature concepts: the ProOceanus pressure housing, and the NASA-Ames developed carbon nanotube (CNT) sensor. Carbon nanotube based gas sensors are considered cutting edge technology, allowing to detect a wide range of environmental and safety related trace gases at relevant sensitivities.
They are low power, and have provided in-situ, real time, automated measurement of chemicals in space, for fire detection, for fuel leak detection, and as health monitoring system. The technical and scientific approach, as well as the current status of the SCUID instrument development will be presented in the proposed paper.
