Result description
NOC has developed a new in situ sensor to make autonomous measurements of dissolved suphide. Based on the lab-on-chip platform developed at the NOC, the system comprises a microfluidic chip, with miniature pumps, valves and electronics, which permits a laboratory chemical analysis of dissolved sulphide to be carried out automatically inside the device and the result stored for later retrieval (the result can also be transmitted if the platform it is attached to supports this capability). The new sensor is the first in situ sensor for dissolved sulphide capable of being deployed at depth (it is pressure rated to 6000 m). It has been successfully demonstrated on a research cruise aboard the RV Mare Nigrum in September 2023.
We present a new in situ sensor for the measurement of dissolved sulphide. We have developed and demonstrated this new sensor for the first time as part of the DOORS project. The sensor is capable of fully autonomous measurement of sulphide at water depths down to 6000 m. It can measure a concentration range from 2.6 to 650 μmol/L. It is capable of making one measurement every 9 minutes. Full details are in a manuscript that is currently being prepared.
Addressing target audiences and expressing needs
- Collaboration
NOC is always looking for further opportunities to collaborate with new and existing partners, to identify and develop new technology, and to test novel technology in locations that generate new data to address current scientific knowledge gaps. We have a commercialization plan for the technology developed by NOC and many of the innovations from previous projects have been now been commercialized.

R&D, Technology and Innovation aspects
The prototype of the sulfide sensor has been tested in various conditions against other methods of determination of sulfide concentration in seawater. Next steps include optimization of the design, developping a product that can be commercialized.
