description
- x in-situ marine nutrient (total oxidised nitrate i.e. nitrite plus nitrate) analysers.
A wet-chemical nutrient analyser is required for use in coastal and offshore marine monitoring. It will be fitted to our autonomous monitoring platforms, specifically a surface mooring (SmartBuoy) for continuous collection of nutrient data. It should be supplied with suitable mounting points.
| - | The instrument should be capable of measuring dissolved total oxidised nitrogen (NO2- + NO3-) in a turbid coastal marine environment with a high degree of sensitivity, accuracy and stability: |
| o | Linear range: 0.1 - 150 umol l-1 |
| o | Analytical uncertainty <1% |
| o | Automatic drift correction using integrated calibration standard |
| - | It must be capable of being integrated with our existing data logger through a RS232 serial data connection. This output should be customisable to match our existing telemetry system. The instrument should also self-log and be able to store at least 4 months of data. |
| - | Reagents should ideally be provided as a service, with instructions for manufacturing our own as a secondary concern. Please provide expected lead times for replacement reagents. |
| - | Form factor, efficient use of reagents, resistance to fouling, low power consumption and depth capability are also assessment criteria. |
| o | Maximum dimensions 1.2 m x 1 m x 0.75 m (height, width, depth) |
| - | The instrument should manage its own power supply (batteries) |
