Instruments

Nutrient Autoanalyzer

Supplied Description:

A 5-channel, continuous flow analyzer was used for dissolved nutrient determinations on the BIG RAPA cruise. Alpkem and Technicon AutoAnalyzer II™ components were used to measure phosphate, ammonium, nitrite, silicic acid and nitrate plus nitrite (N+N). A Keithley model 575 data acquisition system backed by analog strip chart recorders was used to acquire the data. Absorbance data was converted to concentrations using the OSU program NUTCALC.

Instrument Type

Generic Name: Nutrient Autoanalyzer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB04/

Generic Description:

Nutrient Autoanalyzer is a generic term used when specific type, make and model were not specified. In general, a Nutrient Autoanalyzer is an automated flow-thru system for doing nutrient analysis (nitrate, ammonium, orthophosphate, and silicate) on seawater samples.
