User's Manual: NOC LOC Dual Nutrient (Nitrate / phosphate) Sensor. Version 1

Abstract

The NOC LOC Dual Nutrient sensor is a microfluidic sensor capable of measuring two nutrients. It is based on lab-on-chip technology with optical (spectrophotometric) detection. A series of pumps and valves move chemical reagents and mix these with external samples and standards. A coloured reaction product is formed and its optical absorbance is measured using LEDs and photodiodes. This manual describes the basic operation of the NOC LOC dual nutrient nitrate and phosphate sensor. It covers the operation and use of the instrument and procedures that should be followed during a deployment.
