Total Organic Carbon (TOC)

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), recognize TOC as a required test for purified water and water for injection (WFI).

TOC Overview

TOC analyzers can measure:

  • Total carbon (TC)
  • Total organic carbon (TOC)
  • Inorganic carbon (IC)
  • 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

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.
