Precision TOC Analysis Advances Water Quality Monitoring

With more than 45 years of technical experience in water-quality instrumentation, the technology has been developed around rapid, accurate and reliable results. The TOC portfolio is intended to address varied application challenges, using analytical techniques that help track water quality in complex production environments.

To meet different industry requirements for water monitoring, the product line includes TOC analyzers based on combustion, wet chemical oxidation and dual-mode analysis.

Beyond the core analyzers, optional components and accessories are available to extend application flexibility and analytical depth. These options allow testing to be adapted to specific sample types.

• 1030S Solids Module: Designed for solid-sample analysis, extending the instrument's application range.
• TN b Kit: Supports simultaneous measurement of total bound nitrogen, adding another key data point in a single analysis.

Selection depends on the sample matrix, expected organic carbon levels and the oxidation resistance of the organic matter. Combustion methods are generally used for samples that contain difficult-to-oxidize organics, while wet chemical oxidation can be more suitable for low-concentration water samples or particular matrices. Dual-mode instruments are positioned for laboratories that need to handle a mix of sample types.

For non-liquid samples, a solids module can expand the range of analysis. For programs that also require nitrogen data, a TN b kit allows total bound nitrogen to be measured in the same analytical run as TOC, reducing sample handling and adding another dimension to water-quality data.
