Instrument: Total Organic Carbon Analyzer
A unit that accurately determines the carbon concentrations of organic compounds typically by detecting and measuring its combustion product (CO2). See description document at: http://bcodata.whoi.edu/LaurentianGreatLakes_Chemistry/bs116.pdf
TOC analyses were perfomed using a Shimadzu TOC-500 (for 1997 and 1998 samples). The Shimadzu TOC-500 TOC analyzer measures total carbon (TC), inorganic carbon (IC) and total organic carbon (TOC) in water. TC, TOC and IC are measured by the combustion-non-dispersive infrared gas analysis method. Starting in April 2000, a Shimadzu TOC-5000A analyzer with an ASI 5000 autosampler was used.
