Our LAR™ QuickTOCtrace™ pure water analyzer is the most reliable measurement system for the determination of the total organic carbon. The QuickTOCtrace delivers the lowest measuring ranges, which uses UV oxidation and differential conductivity measurement to determine organic contamination, making it ideal for TOC measurement of ultra-pure water. It is a compact and intuitive analyzer with a short reaction time – first results are available within 30 seconds. It combines conductivity and UV oxidation to provide continuous TOC measurement in the 0.1 – 1,000 ppb range. Easy-to-use, this low-maintenance online analyzer quickly, and reliably monitors low-level TOC and is particularly well-suited for applications in the pharmaceutical industry (WFI, HPW, PW), and wherever ultra-pure water (UPW) is used.

Using UV oxidation and differential conductivity measurement, the QuickTOCtrace reliably determines organic concentration results within 30 seconds.
This instrument is designed to monitor the quality of ultra-pure water with low concentrations of Total Organic Carbon (TOC). It is capable of measuring TOC concentrations as low as 0.5 parts per billion (ppb) in water samples. It is particularly useful for monitoring the quality of water used in critical applications where even low levels of TOC can have a significant impact on product quality and performance.
The QuickTOCtrace analyzer is used in industries that require ultra-pure water:
In the semiconductor industry, for example, ultra-pure water with low TOC levels is required for cleaning and rinsing of microchips during the manufacturing process. Even small amounts of TOC can cause defects or contamination, resulting in lower yields and reduced product quality.
Similarly, in the pharmaceutical industry, ultra-pure water with low TOC levels is used in the production of drugs and medical devices to ensure that they meet regulatory standards and are safe for use.

The QuickTOCtrace is an online system working on the basis of the traditional continuous flow process with conductivity detection. UV oxidation using the “direct surface” process guarantees highest precision thanks to highly sensitive conductivity sensors. In differential conductivity measurement, the initial conductivity before oxidation, as well as the conductivity after the treatment of the sample, are measured. The TOC concentration results from the difference obtained from subtracting the first, lower conductivity measurement from the second, higher one.
The verification of the TOC result is carried out using periodical implementation of the system suitability test and complies with the standards prescribed by the US pharmacopoeia, as well as the European pharma regulation (European pharmacopoeia). The QuickTOCtrace software enables a quick and simple initiation of the SST at any time and offers automatic data evaluation as well as automatic implementation of the testing procedure. The automized functions of the SST allow a high standard of safety and minimized operation costs in controlling the water.
