Process TOC Analyser

Tekmar’s newest addition to the TOC analyzer product line, the Torch, utilizes a patent pending Static Pressure Concentration (SPC) for the analysis of TOC/TN using high temperature combustion.

The Torch Analyzer contains a built in autosampler with three vial rack choices and PC driven control. This features automated calibration and Intellidilution which automatically dilutes over-range samples to within the working calibration range. Maintenance is simplified by design allowing easy access to all areas of the unit.

All of these features and competitive price positioning make this system ideal in keeping costs down and maintaining productivity in the laboratory.

TOC is a popular analytical technique in water quality testing, as seen in many official analytical methods today. The United States Pharmacopoeia (USP), European Pharmacopoeia (EP) and Japanese Pharmacopoeia (JP), recognizes TOC as a required test for purified water and water for injection (WFI). As stated in USP method <643> on Total Organic Carbon:

"TOC is an indirect measure of organic molecules present in pharmaceutical waters measured as carbon. Organic molecules are introduced into the water from the source water, from purification and distribution system materials, and from biofilm growing in the system. TOC can also be used as a process control attribute to monitor the performance of unit operations comprising the purification and distribution system."

TOC has also found wide acceptance in the biotechnology industry to assist in the validation cleaning procedures, especially clean-in-place (CIP). TOC concentration levels can be used to track the success of these cleaning procedures.
Since the relationship between Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and TOC was established in the 1970s, TOC analyzers have become an analytical backbone in many water treatment and quality control laboratories worldwide. In environmental applications, TOC is an essential environmental parameter used to measure wastewater from municipal and industrial sources.

The task of choosing a Total Organic Carbon (TOC) analyzer brings one to consider the many instruments currently on the market. This becomes more difficult when faced with understanding that Total Organic Carbon (TOC) analyzer manufacturers may use different oxidation techniques which could effect the analytical data. This article highlights some analytical differences between the two major Total Organic Carbon (TOC) oxidation techniques and offers suggestions for a process to base the choice upon the user’s unique needs.
Since the relationship between BOD, COD, and TOC was established in the late 1970s, Total Organic Carbon (TOC) analyzers have become an analytical backbone in many water treatment and quality control laboratories worldwide. Important environmental and pharmaceutical regulations such as US EPA’s Information Collection Rule and United State Pharmacopoeia (USP) TOC in Water for Injection (WFI) have only increased the importance of the measurement.
Over the years many Total Organic Carbon (TOC) analyzers have been introduced by various manufacturers which use different oxidation technologies. The development of different oxidation technologies were used to gain an analytical and marketing advantage against a competitive manufacturer. Currently, two major oxidation technologies dominate the Total Organic Carbon (TOC) market place: combustion and UV/persulfate. The late 1980s saw the start of a major debate between which technique was best suited for testing for Total Organic Carbon (TOC). This paper is designed to highlight the advantages and disadvantages of both techniques in a balanced and analytical manner. This will give users appropriate information to make an informed decision as to which technique serves their needs the best and explain disparities between the two techniques
