TOC Analysis Methods

Analysis typically begins with a measurement of TC (total carbon) and does not differentiate between Total Organic Carbon and Total Inorganic Carbon. Inorganic carbon can come from many mineral sources. To get a useful Total Organic Carbon measurement required for water quality analysis, inorganic carbon needs to removed from the equation. Therefore the sample needs to be purged of inorganic carbon to yield a measurement of the remaining carbon to quantify Total Organic Carbon.

TOC Analysis Procedures

The procedure for TOC analysis depends on the application. High purity water used within the pharmaceutical industry and the semiconductor industry requires a different method than water used within municipal water plants or water steam cycles.

For high purity water where the measurement range is in the parts per billion PPB an Analyzing unit like the Swan AMI Line TOC is optimal.  Adopting a reagent free UV oxidation process, two high precision two-wire conductivity electrodes are used to determine differential conductivity. This in turn leads to the level of accuracy required. In the case of the Swan instrument, temperature compensation is also integrated within the system which is a requirement for highly accurate results.

For typical analysis of condensate, potable water or surface water where measurement in the parts per million is required, the more common two stage process as adopted within the Seres TOC Evolution VUV is required.

  1. Stage one is achieved By purging the sample after adding acid, the inorganic carbon IC is converted to CO2 and completely extracted from the sample.
  2. Stage two is the measurement  performed after the IC is removed to return a measurement. This method can vary.

In the case of the Seres TOC Evolution VUV, the ‘VUV’ refers to a Vacuum Ultraviolet Reactor. The stage two sample is injected into the oxidation reactor. UV directly oxidizes the organic matter which turns into CO2. The CO2 produced is then detected by an NDIR detector (non-dispersive infra-red).

TOC Analysis in Pharmaceutical Industry

Pharmaceutical and Biotechnological Applications require strict regulations and audits where reliable and continuous monitoring is essential. The AMI LineTOC, TOC Analyzer, meets all requirements. As a complete monitoring system it allows measurement of TOC levels in purified water network with all the necessary documentation and continuous analyzing for constant surveillance of the process.

TOC Analysis Interferences

The non-dispersive infrared analysis (NDIR) method as adopted by the Seres TOC Evolution VUV offers the only practical interference-free method for second stage CO2 measurement. NDIR only measures the result of oxidization within the reactor.
