Total Organic Carbon (TOC) is an aggregate measurement used by water treatment plants to indicate the amount of organic contamination from natural and non-natural sources. However, it is sometimes desirable to understand what organic compounds make up a TOC value. The M9 SEC DOC Detector was developed to operate as part of an HPLC Size Exclusion Chromatography (SEC) system to separate and quantify both aromatic and nonaromatic organic fractions as a function of molecular weight.

However, it is sometimes desirable to understand what organic compounds make up a TOC value. The M9 SEC DOC Detector was developed to operate as part of an HPLC Size Exclusion Chromatography (SEC) system to separate and quantify both aromatic and nonaromatic organic fractions as a function of molecular weight. Obtaining a complete picture or ‘footprint’ of organic size fractions present in source water, process waters, and finished water can help operators make smarter treatment decisions to optimize processes for time savings, cost savings, and ensure discharge quality. The combined HPLC SEC UVA + DOC system discussed in this article provides a better understanding of all organics present as opposed to only those that have a chromophore or fluorophore. The resulting information can be correlated to size fractions of specific contaminants or functional groups. The aim of this article is to discuss advantages and limitations of the classical TOC method in comparison with new enhanced techniques like Total Organic Carbon Size Exclusion Chromatography (TOC-SEC). » weiterlesen» einklappen
