CEFAS21-16 RFQ for 2x in situ Marine Nutrient Analysers

Cefas (The Centre for Environment, Fisheries and Aquaculture Science) the 'Authority', is an Executive Agency of the UK Government's Department for Environment, Food and Rural Affairs (Defra). It is an applied science agency that primarily supports government decision making whilst extending its reach across the public sector, the EU and wider markets where possible in regard to marine and closely related environments. Requirement:

2 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)
