Segmented flow analyzer

Description

The AA500 segmented flow analyzer has been developed to measure inorganic nutrients in seawater, and is used by several leading marine institutes around the world. The device is ideally suited to measure nutrients (ammonia, nitrate and phosphate) in the lower range, such as in oceanic samples. Mesocosm or aquarium studies requiring nutrient monitoring also greatly benefit from this machine.
