A total organic carbon analyzer (also referred to as TOC analyzers) measures the amount of total organic carbon present in a liquid or water sample. TOC detection is important because of the effects that TOCs may have on health, not to mention the environmental effects and implications for the pharmaceutical manufacturing processes. Since all total organic carbon analyzers only measure total carbon, a TOC analyzer always requires some accounting for the inorganic carbon (IC) that is always present.
TOC analyzers, including a portable TOC analyzer, utilize the same basic technique where acid is added to the liquid sample to remove IC. At this point, the IC is converted into carbon dioxide gas. It is then stripped out of the liquid by a carrier gas where the remaining inorganic carbon-free sample is then oxidized and the carbon dioxide generated from the oxidation process is directly related to the TOC total organic carbon in the sample. There are several methods for introducing the sample to TOC analyzers, including using a syringe, autosampler, and loop sampling. An important specification for total organic carbon analyzers is the measuring range. Carrier gas flow rate, average analysis time and process temperature are important as well for total organic carbon analysis.

| Description | The TOC-L series of TOC analyzers adopts the 680°C combustion catalytic oxidation method, which was developed by Shimadzu and is now used worldwide for such methods as EPA 415.3, SM 5310B, and ASTM D7573. While providing an ultra-wide range of 4 µg/L to 30,000 mg/L, these analyzers boast a The TOC-L series of TOC analyzers adopts the 680°C combustion catalytic oxidation method, which was developed by Shimadzu and is now used worldwide for such methods as EPA 415.3, SM 5310B, and ASTM D7573. While providing an ultra-wide range of 4 µg/L to 30,000 mg/L, these analyzers boast a detection limit of 4 µg/L through coordination with NDIR. This is the highest level of detection sensitivity available with the combustion catalytic oxidation method. In addition, the combustion catalytic oxidation method makes it possible to efficiently oxidize not only easily-decomposed, low-molecular-weight organic compounds, but also hard-to-decompose insoluble and macromolecular organic compounds.
Features - Capable of TC, IC, TOC (= TC-IC), and NPOC measurement; options enable POC (volatile organic carbon), TOC via POC + NPOC, and even TN (total nitrogen) measurements
- The blank check function evaluates system blanks by measuring ultrapure water processed automatically within the instrument
- The automatic dilution function enables measurements up to 30,000 mg/L
- Automatic sample acidification and sparging
- The automatic dilution function reduces sample salinity, acidity, and alkalinity, significantly extending the period of use of catalysts and combustion tubes (The period of use depends on the sample and measurement conditions.)
- Stat or priority samples can be added at any time to the analysis schedule without interrupting operation even when an autosampler is used
Control software provided as standard with PC-controlled models provides excellent operability and a wealth of functions to fully support analysis work. In addition, security and integrity are maintained, protecting valuable customer data and helping to enable compatibility with electronic records/electronic signature regulations....

Conventional on-line TOC analyzers often struggle to detect hard-to-oxidize As semiconductor miniaturization continues to advance, even trace-level organic contamination in ultrapure water can directly impact process stability and yield, making precise, reliable monitoring of TOC essential. Conventional on-line TOC analyzers often struggle to detect hard-to-oxidize compounds such as urea, which can persist after purification and compromise fabrication processes. Developed with direct input from leading semiconductor manufacturers, the TOC-1000e S online total organic carbon analyzer addresses these challenges by delivering enhanced sensitivity and real-time monitoring capabilities tailored to next-generation fabrication environments.
Features include:
- High-sensitivity detection of hard-to-oxidize organic contaminants, including urea, promoting more accurate assessment of ultrapure water quality
-
Simplified flow path that enables real-time monitoring and rapid response to contamination events
-
High-visibility touch panel with intuitive, color-coded status indicators supports efficiency daily operation and data review
-
Only requires annual onsite maintenance for maximum uptime
-
Supports a variety of data output formats
-
Network connectivity allows users to monitor data remotely through a standard web browser without dedicated software
-
Compact design weighing approximately 3 kg makes it suitable for benchtop, wall or pipe-mounted installation
