After releasing its first TOC products, Shimadzu rapidly improved them, launching the TOC-401, TOC-402, and TOC-10A the next year. TOC-10A allowed manual injection into a 950°C furnace, with CO2 peaks printed and measured by peak height.
This improved laboratory analyzer used ambient air purified for high-sensitivity TOC analysis. Enhanced injection ports and dual furnaces allowed for precise measurements. It marked Shimadzu's first international debut at an exhibition in Tianjin, China.
The TOC-500 introduced the 680°C combustion method, reducing maintenance issues from salt in samples. With simplified catalyst replacement, automated peak integration, and global availability, it gained popularity in Europe and the US.
Featuring a revolutionary syringe pump with a 4-port valve and sample slide injector, this model simplified operation. It supported autosamplers, improving accuracy and labor efficiency. The measurement range extended to lower ppb levels, enabling pure water analysis.
Featuring the first Shimadzu PC software, "TOC Control," this model became essential for pharmaceutical applications like pure water and cleaning validation. The TOC-5050(A) variant was introduced for environmental analysis.
Utilizing the 680°C combustion method and an 8-port valve, this online TOC analyzer featured automatic dilution, particle sampling, and POC measurement. It ensured reliable analysis and rapid response for environmental protection.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
