Many industries, including
pharmaceuticals and water quality,
often measure a sample’s total organic
carbon (TOC). These instruments
come in various forms, including
some that use combustion, others
that rely on ultraviolet persulfate
oxidation, and so on. Some TOC
analyzers also combine approaches
to oxidation. According to Tammy
Rellar, TOC product manager at
Teledyne Tekmar (Mason, OH),
“Operational efficiency is paramount
in today’s TOC market.”
A mainstay of environmental and quality control chemistry, TOC analyzers measure the carbon content of dissolved and particulate organic materials in water. The carbon measured may arise from any combination of living or dead organisms and chemical
The amount of carbon in an organic
compound makes up the so-called
total organic carbon (TOC), which
serves as a crucial metric in a wide
range of processes. For instance, TOC
can indicate the quality of water or
the cleanliness of a
