Benchtop Total Organic Carbon

and Total Nitrogen

Total organic carbon, or TOC, analyses are widely used to assess process inefficiencies, leaks within plumbing, and
for regulatory compliance when process water is discharged from the facility. As organic precursors, reactants, and
products come into contact with process water, some of those materials are incorporated into the water and can be
detected by using TOC as a non-specific proxy for the overall organic contamination within the sample.

Shimadzu is the industry leader in combustion TOC analyzers and offers benchtop and online versions to suit a
variety of applications and needs. They are built around the industry-first and time-proven 680° C furnace for
efficient oxidation of carbon within the sample. Shimadzu’s TOCs are the sure solution for TOC and other sum
parameters analysis of process water, wastewater, sludges, and brines.

Total Organic Carbon Analyzer
TOC-L

The TOC-L series is Shimadzu’s flagship benchtop combustion TOC analyzer. Its simple,
reliable operation is the benchmark for the combustion TOC market. It features:

• Color screen on instrument for stand-alone operation or control from local PC
• Autosampling options for up to 96 samples
• Low cost of operation with no proprietary reagent cartridges
• Optional total nitrogen (TN) unit for TOC and TN analyses
• Accurate, precise results, even with high-salt / brine sample matrices
