Total Organic Carbon (TOC)

TOC Theory
TOC is a popular analytical technique in water quality testing, as seen in many official analytical methods today. The United States Pharmacopoeia (USP), European Pharmacopoeia (EP) and Japanese Pharmacopoeia (JP), recognizes TOC as a required test for purified water and water for injection (WFI). Click here for additional information on the TOC Theory.

TOC Overview
TOC analyzers can measure:
  • Total carbon (TC)
  • Total organic carbon (TOC)
  • Inorganic carbon (IC)
  • Purgeable organic carbon (POC)
  • Nonpurgeable organic carbon (NPOC)
TOC measurement involves:
  • Oxidizing organic carbon in a sample
  • Detecting and quantifying the oxidized carbon (CO2)
  • Presenting the result in units of mass of carbon per volume of sample

NDIR Pressurization Overview
Pressurized detection, or static read, is a technique used for concentrating the CO2 produced by the oxidation of the sample. The technique can be used for both qualitative and quantitative analysis. In this section the basics of the pressurization technique will be described. Click for more on NDIR Pressurization.
