The instrument detects nitrate and nitrite (up to 350 µM, 21.7 mg/L as NO3-) with a limit of detection (LOD) of 0.025 µM for nitrate (0.0016 mg/L as NO3-) and 0.02 µM for nitrite (0.00092 mg/L as NO2-). This performance is suitable for all natural waters except for the oligotrophic open ocean. Beaton et al. (2012) has a full description of the technology."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL1103" ; skos:note "accepted"@en ; skos:prefLabel "National Oceanography Centre (NOC) Nitrate and Nitrite v3.2c Lab-On-Chip (LOC) sensor"@en ; skos:related .
