Instruments

Ion Chromatograph

Supplied Name: Dionex Ion Chromatograph

Supplied Description:

Instrument Type

Generic Name: Ion Chromatograph

Generic Description:

Ion chromatography is a form of liquid chromatography that measures concentrations of ionic species by separating them based on their interaction with a resin. Ionic species separate differently depending on species type and size. Ion chromatographs are able to measure concentrations of major anions, such as fluoride, chloride, nitrate, nitrite, and sulfate, as well as major cations such as lithium, sodium, ammonium, potassium, calcium, and magnesium in the parts-per-billion (ppb) range. (from http://serc.carleton.edu/microbelife/research_methods/biogeochemical/ic.html)

Nutrient Autoanalyzer

Supplied Name: Technicon TrAAcs AutoAnalyzer

Supplied Description:

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.

Stainless Steel Sampling Bottle

Supplied Description:

Near-surface water (1 m depth) will be collected using a stainless steel sampling bottle.

These bottles were custom made (welded stainless steel) by Fletcher Manufacturing, Bowling Green, OH).

Instrument Type

Generic Name: Stainless Steel Sampling Bottle

Generic Description:

A stainless steel sampling bottle used for collecting near surface samples (not a GO-FLO bottle)

Turner Designs 700 Laboratory Fluorometer

Supplied Description:

For analysis by fluorometry, samples are extracted in 90% acetone (24 h at -20° C) and chlorophyll measured in a TD-700 fluorometer (Turner) using the non-acidified approach (Welschmeyer, 1994)

Instrument Type

Generic Name: Turner Designs 700 Laboratory Fluorometer

Acronym: TD-700

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0510/

Generic Description:

The TD-700 Laboratory Fluorometer is a benchtop fluorometer designed to detect fluorescence over the UV to red range. The instrument can measure concentrations of a variety of compounds, including chlorophyll-a and fluorescent dyes, and is thus suitable for a range of applications, including chlorophyll, water quality monitoring and fluorescent tracer studies. Data can be output as concentrations or raw fluorescence measurements.
