  • TOC Analysis for Standard Methods 5310B: High-Temperature Combustion Method

    Introduction Total Organic Carbon (TOC) is a rapid method that analyzes for organic carbon and expresses the result as the amount of carbon found. It is a non-specific method unable to distinguish between various organic species and only indicates that organic carbon compounds are present. Organic carbon analyzers operate by the determination of the amount of total carbon present in a ...

  • Characterization of Algae by TOC Measurement

    Global warming due to the excessive use of fossil fuels is becoming a problem which has prompted and accelerated the search for alternative fuels. Among the more attractive alternatives is biomass fuel, which is attracting considerable attention. Microalgae can be used for the production of oil without competing with food production, and to a greater extent than other biofuels, its ...

  • Measuring TOC in Brine Solutions

    In the chlor-alkali and electrolysis industries, as well as many others, there is a need to analyze for TOC in samples containing high salt concentrations. These samples can range from sea water, which is typically 3% salt, up to brine solutions containing 28% salt. Shimadzu’s TOC-L with the high salt kit (P/N 638-93176-01 for N model & P/N 638-93176-02 for H model) is well suited for ...

  • New TOC sensor wins Gold IBO award for portable instrument design

    In 2006, the USEPA singled out the distribution system as the most vulnerable component of a utility’s drinking water system. In response, many waterworks are taking a closer look at how they may protect the public’s drinking water. One option is to place online water quality panels throughout the distribution system to detect a change in the baseline water quality. The cost of implementing a ...

  • Organics Monitoring (TOC)

    Total organic carbon (TOC) testing is the traditional method for determining organic matter in water. However there is a far more practical, affordable and often more useful way to measure organic matter. UV absorbance testing (UVA) is rapidly becoming the preferred method of measuring organics even when the levels of organics being measured are very small. Organic Matter Organic ...

  • TOC analyser improves lab efficiency

    Leading instrumentation company HACH LANGE is helping a number of key customers save valuable time and costs with its new IL550 TOC-TN analyser. TOC analysis is vitally important in applications ranging from power generation, wastewater, drinking water, surface water and ultrapure water, to agricultural soils, contaminated land and food. HACH LANGE analysers therefore offer a range of options ...


  • Measurement of TOC in High-Salt Sample

    The quantity of organic matter in seawater is important in the research and monitoring of marine pollution as an indicator of organic pollution. The salt content in seawater is typically about 3.5 %, but using the Shimadzu total organic carbon analyzer, it is possible to measure the TOC directly without dilution or other pretreatment procedures. Here, we introduce an example of measurement of ...

  • Monitoring of Algae Growth by TOC Measurement

    Global warming due to the excessive use of fossil fuels is becoming a problem which has prompted and accelerated the search for alternative fuels. Among the more attractive alternatives is biomass fuel, which is attracting considerable attention. Microalgae can be used for the production of oil without competing with food production, and to a greater extent than other biofuels, its ...

  • Measurement of TOC in Perfluorochemical (PFOS) Solution

    PFOS is an extremely stable compound with strong carbon - fluorine bonds, and reports of its accumulation in wildlife and the environment have attracted international attention and concern, leading to the designation of PFOS as a persistent organic pollutant (POP).The persistent nature of PFOS prevents oxidative decomposition using wet chemical oxidation TOC analyzers; however, the Shimadzu ...

  • Real-time TOC tightens effluent control at Greencore

    A food manufacturing facility in Selby has installed a new continuous TOC (Total Organic Carbon) monitor, ‘the BioTector’ which has dramatically improved the site’s capability to refine and improve the plant’s wastewater treatment process. As a result the plant is better able to quickly respond to changes in the influent. Greencore Foods is a leading player in the food ...


  • Choosing the appropriate TOC analyzer for your application?

    In choosing a Total Organic Carbon (TOC) analyzer, among the many factors that need to be given consideration are not only the current instruments and their accessories available on the market, but specifically to their method of sample oxidation in relation to the sample matrix. Different oxidation techniques may affect the analytical data due to the components within the sample matrix. This ...

  • TOC Determination in Solid Samples using the Suspension Method

    The TOC content in solids plays an important role in the classification of soils, sludges and sediments. According to the German Ordinance on Environmentally Compatible Storage of Waste from Human Settlements, TOC in solid materials is one of the key parameters for the characterization of wastes as part of the acceptance control of landfills. This important control measure requires a ...

  • TOC System Suitability Test for Sterile Water

    The United States Pharmacopeia (USP) specifies that total organic carbon (TOC) content be used for management of organic impurity values permitted in bulk purified water, water for injection, in addition to sterile purified water and sterile water for injection. According to USP, TOC analyzers to be used for sterile water must satisfy the TOC system suitability test using test water ...

  • TOC monitoring upstream of paper mill wastewater treatment facility using online TOC analyzer

    At wastewater treatment facilities of various types of manufacturing plants, pollution load monitoring (upstream monitoring) is becoming increasingly important to ensure appropriate and stable operation and water pollution accident prevention.
