In 2005, BodyCote International selected a HiPerTOC bench top analyzer from Thermo Fisher Scientific for its environmental inorganic and organic carbon analyses of water samples.

In 2005, BodyCote International selected a HiPerTOC bench top analyzer from Thermo Fisher Scientific for its environmental inorganic and organic carbon analyses of water samples. This generated significant cost savings and provided immediate benefits in productivity and to their personnel.

BodyCote Testing Group is one of four business units forming the UK-based BodyCote International Plc. The Testing Group business unit consists of over 60 accredited laboratories operating throughout Europe, the Middle East and North America providing testing, research and development, and i consulting services to all sectors of industry. Bodycote International operates 250 facilities worldwide, including over 45 laboratories in the Testing Group business unit as well as its Environmental division based in Canada.

Based in Toronto, BodyCote’s Environmental Division offers an extensive network of testing and development facilities and is one of the top 10 leading analytical laboratories in Canada, employing more than 300 staff. The lab also is accredited to ISO (Guide) 17025 by the Quebec Ministry of Environment and by the Standards Council of Canada. As does its environmental division, BodyCote Testing also focuses its activity on metal testing, polymers and plastics, health sciences, engineering and transportation, and product testing.

The Canadian environmental division, in Quebec City, employs 85 staff and specializes in providing comprehensive testing in the fields of inorganic analysis, organic analysis and ecotoxicology for waters, air and soils. About 25% of its business comes from the water industry and 25% from government water organizations and public sector contracts, while 50% consists of groundwater and soil analysis. The lab analysis company relies heavily on TOC analysis as an important technique for its analysis of matrices in water samples within the laboratory.

The Need for TOC Analysis

Total organic carbon (TOC) analysis is a valuable screening process for any organic carbon present in water, and is the fastest growing process analytical method among many industries for a variety of applications. It’s estimated that, overall, the worldwide value of the process TOC market will grow at a compound annual growth rate (CAGR) of over 11% between 2002 and 2007. With introduction of the strict EN 1484 and EPA 415.1 environmental regulations, compliance with these regulations is of the highest importance for environmental contract and industry laboratories monitoring the quality of wastewater and drinking water. TOC indicates the presence of any organic compounds, some of which can be potentially dangerous in the cleaning process and may react with disinfectants to form toxic and even carcinogenic compounds resulting in interference with wastewater treatment processes and production of potable water.

To adequately measure for TOC, the U.S. Environmental Protection Agency (EPA) set a detection limit of 0.500 mg/L. Instruments capable of analyzing TOC must meet and/or exceed these detection limit requirements. Generally, all TOC analyzers employ the same basic technique. A liquid sample is introduced to an inorganic (IC) removal stage, where acid is added to the sample. At this point, the IC is converted into carbon dioxide (CO2) gas that’s stripped out of the liquid by the sparge carrier gas. The remaining inorganic carbon free sample is then oxidized and CO2 generated from the oxidation process is directly related to the TOC in the sample.

Analysis methods TOC analyzers use to oxidize and detect organic carbon may be one or more of the following: combustion, UV/persulfate oxidation, ozone promoted or UV fluorescence. A method for introducing samples to the analyzer is via a syringe. Another is loop sampling, in which the sample loop introduction system allows repeatable analysis over a wide range of concentrations while avoiding inherent dead volumes of syringe-based systems. Via autosamplers is another option. Here, the liquid autosampler removes specific sample volumes from a standard vial and transfers the sample to the common analysis vessel - a common technique used for unattended analysis.

Complications with TOC Analysis

Prior to selecting the HiPerTOC unit, BodyCote used a 10-year-old TOC analyzer for its sample analysis. The broad sample range of customers’ samples posed a problem for a single instrument to do all the sample analyses. As well as needing to replace an old instrument, BodyCote’s customers were being affected by instrument downtime and the staff were needing to dedicate more time to maintenance than necessary. After running a dirty water sample, the old TOC instrument needed to run five blank samples. In 2005, the company made a decision to search for a replacement to its incumbent TOC analyzer while looking for a faster, more cost-effective, less disruptive solution.

Francois Aube, operations manager of the chemistry laboratory, comments: “We looked at our existing supplier’s model to specify a new replacement TOC analyzer - it needed more work such as blank samples to meet our current specification. The HiPerTOC is like having two instruments in one, with its wet-chemical reactor for lower detection limit and high temperature reactor for dirty samples. This is why we chose Thermo”. Report 1 shows results of the detection limit study by Bodycote using the UV/persulfate technique.

Due to increasing pressures faced by water testing facilities to meet regulatory requirements, it’s important for these companies to have the necessary instrumentation allowing them to meet customers’ demands. Fortunately, BodyCote found that, requiring little or no training, the Thermo Scientific analyzer resulted in greater productivity and was able to run samples thoroughly and efficiently, and with greater ease. This flexibility was further enhanced with a standard autosampler this instrument incorporates.

By achieving a very low detection limit of 0.04 ppm, this analyzer exceeds detection limit guidelines and is able to respond to scientists’ needs working in water treatment, pharmaceutical, food and beverage and wastewater industries. Downtime and disruption are potential problems facing companies daily, which in turn can disrupt business profitability and production. For roughly 10 years, BodyCote had struggled with its sample analysis, using its old TOC analyzer, which resulted in high downtime due to essential maintenance issues.

Benefits from Installation

BodyCote decided to install the new analyzer, first, to increase productivity. The company anticipated this replacement instrument would be able to cope with the high number of sample analyses required daily and, more importantly, that the instrument’s robustness would also cope with “dirtier” samples that couldn’t be analyzed efficiently with the previous system. The analyzer is equipped with four different oxidation techniques for TOC analysis, high temperature oxidation, UV/persulfate, UV ultrapure and ozone promoted. The company found that the integrated solution substantially reduces the cost per analysis and ensures major productivity gains and time savings thanks to the integrated 63-position XYZ autosampler.

The lab analysis company also sought to improve its efficiency and accuracy of sample analyses. It found that the new analyzer provided accurate and precise results at both high and low concentration ranges in a wide variety of sample types ranging from dirty wastewater to clean drinking water. Samples analyzed using the previous TOC instrument occasionally had to be sent away for external testing. With the new unit, though, BodyCote’s Testing Group organization is now able to run all customers’ sample analysis on a daily basis and 100% of analyses are now carried out onsite. Table 1 shows results of the recovery study by Bodycote using the high temperature technique. The concentration of SO4 is a measure of the salinity of the sample.

BodyCote has reduced training costs substantially due to the instrument’s ease of use, with even new personnel being able to operate the instrument. It has allowed sample analysis runs to be carried out by its technicians with minimal training and sample runs no longer require senior technicians to be present in the laboratory. The size of this instrument was extremely favorable for the laboratory due to its smaller footprint, which saved space for other operations.


There are certain criteria to be taken into consideration when evaluating the need for a TOC analyzer. Firstly, the most important specification for TOC analyzers is the measuring range. Carrier gas flow rate, average analysis time and process temperature are also important. Furthermore, accuracy and resolution are important considerations.

The Thermo Scientific analyzer offers improved ease of use, lower detection limits, less downtime and improved accuracy. With minimal training, the company’s analyzer has enabled the materials testing company to increase productivity and meet its ever increasing customer demands. Additionally, the integrated auto sampler reduced costs per analysis and its small footprint saves space in the laboratory.

BodyCote’s Aube stated: “This solution has been operating beyond expectations. The HiPerTOC instrument has been online for a year now and dirtier samples are easier to handle - they do not break the instrument! In this first year, we have yet to find a sample we cannot analyze. We are very pleased with the quality and efficiency of the water samples analyzed with this instrument and we look forward to many more years of problem free analyses”.
