Introduction to Total Organic Carbon (TOC) in water

An essential guide

Total Organic Carbon (TOC) is a critical parameter in water quality assessment, crucial for industries varying from pharmaceuticals to environmental management. At Aemas, we specialise in providing state-of-the-art TOC analysers to ensure that your water quality meets the purity standards and regulations. Aemas has collaborated with Teledyne Tekmar, a division of Teledyne Labs, acclaimed for their expertise in pioneering innovative analytical technologies. This guide delves into what TOC is, its importance, and how it’s measured, providing an overview tailored for professionals seeking to enhance their operational and environmental practices.

What is total organic carbon?

Total Organic Carbon (TOC) refers to the amount of carbon found in organic compounds within a sample, for example water. It serves as a broad indicator of quality, revealing the presence of organic materials that could affect the level of purity. Understanding TOC is vital for industries that rely on high-quality water for their processes.

The importance of measuring TOC

TOC is more than just a number on a test report; it is a comprehensive indicator of water’s organic content. High levels of total organic carbon can lead to issues such as increased bacterial growth, corrosion, and inefficiencies in industrial processes. By defining and controlling TOC, companies can significantly improve their operational efficiency and reduce environmental risks. The measurement of total organic carbon is essential for several reasons:

  • Regulatory compliance: Many industries are required to monitor these levels to comply with environmental regulations that govern water purity.
  • Process control: In sectors like semiconductor manufacturing and pharmaceuticals, high levels of TOC can indicate contamination that might compromise product quality and safety.
  • Environmental impact: Monitoring these TOC in natural water sources helps assess the impact of discharges and runoff, supporting the conservation efforts and management of aquatic ecosystems.

How is TOC measured?

TOC measurement can be performed using various techniques, with combustion oxidation and UV/persulfate oxidation being the most common. These methods involve oxidising the organic matter to carbon dioxide, which is then quantified to estimate the TOC level. To enhance our capabilities in this area, Aemas has partnered with Teledyne Tekmar, a division of Teledyne Labs, known for their expertise in developing innovative analytical technologies.
