This instrument is described in this dataset: https://www.ncei.noaa.gov/data/oceans/ncei/ocads/metadata/0123467.html

"Two systems consisting of a coulometer (UIC Inc.) coupled with a Dissolved Inorganic Carbon Extractor (DICE) inlet system. DICE was developed by Esa Peltola and Denis Pierrot of NOAA/AOML and Dana Greeley of NOAA/PMEL to modernize a carbon extractor called SOMMA (Johnson et al. 1985, 1987, 1993, and 1999; Johnson 1992)"

Hi @lqjiang, many thanks for your request.

For these types of instruments that use coulometric titration, a suitable L05 category to use would be:

titrators: http://vocab.nerc.ac.uk/collection/L05/current/LAB12/

We would not want to create a more specific L05 category that describes the types of measurement e.g DIC in this case. If you would like this instrument to be added to the L22 collection, please put in a request at: https://github.com/nvs-vocabs/L22/issues
