1998
TOC-4100
Introducing TNb analysis, this model connected a chemiluminescence detector for combined TOC and TNb measurement. It featured automated samplers, dilution capabilities, and flexible configurations for various applications.
2000
TOC-V C
Featuring an 8-port valve, expanded applications, and a new NDIR detector with auto-zero function, the TOC-V series became a best-seller. Enhanced "TOC-Control V" software supported GMP/GLP compliance.
2002
TOC-V W
Utilizing UV irradiation, persulfate, and heat for oxidation, the TOC-V wet chemical analyzer allowed higher injection volumes and lower detection limits. It was ideal for precise measurements in pure water analysis.
2003
TOC-4110
Combining TOC-V improvements, the TOC-4110 featured a single beam NDIR detector with auto-zero and a miniaturized TN detector. Advanced sampling units and a high salt combustion tube reduced maintenance costs.
2011
TOC-L
With the proven 680°C catalytic oxidation method, the TOC-L series offered modularity, electronic gas flow control, and a high salt combustion tube. These advancements reduced maintenance and energy consumption.
2012
TOC-4200
Designed for robust, unattended operation, the TOC-4200 included a color touchscreen for easy use. It featured a high-sensitivity kit, extended range up to 50,000 mg/L, and reduced maintenance costs.
2021
TOC-1000e
Specializing in online ultra-pure water analysis, the TOC-1000e had a 0.1 µg/L detection limit and a mercury-free excimer lamp. "Active Path" technology and easy maintenance supported compliance with pharmacopoeia regulations.
TOC Stories
Throughout its 150-year history, Shimadzu has gathered numerous stories that exemplify its role in the advancement of analytical technology. Each narrative reflects the contributions of individuals and the evolution of innovations across various fields. Below, we present some of these stories that highlight key milestones in our journey and the impact they have had.
TOC analysis in the quest to achieve carbon neutrality
Achieving carbon neutrality, a significant objective in the battle against climate change, demands a careful balance between carbon emissions and removals. Disturbances to the natural carbon cycle exacerbate climate challenges. TOC analysis assumes a vital role in measuring carbon dynamics, assessing materials that sequester carbon, like concrete, and promoting sustainability. It empowers the process of closing the emissions loop for a greener future.
The role of water quality in power-to-gas applications
Process Analytical Technology (PAT) can transform the production of green hydrogen in our future energy systems. Instruments like the Shimadzu TOC-1000e enable early detection of impurities in water, a crucial step in the electrolysis process. This technology not only aids in predictive maintenance of electrolyzers but also plays a pivotal role in the decarbonization of key industries. Better water quality monitoring is a cornerstone in the journey towards a sustainable future.
How to keep water clean beyond its production
"Drinking water is a strictly regulated commodity in Europe. But how is safety ensured during its journey from the waterworks to the consumer?
Discover the pivotal role of TOC analysis and learn how TOC analyzers assist manufacturers of pipes and materials in contact with drinking water to comply with the European Drinking Water Directive (EU) 2020/2184, Article 11.
