The Breakthrough Path of Domestic TOC Analyzer: Practice and Exploration of Breaking Import Monopoly

In June 2025, the ultra pure water system of a leading semiconductor company suddenly triggered an alarm, causing abnormal fluctuations in TOC values. In the emergency, they did not choose traditional imported brands, but instead used Shanghai Botuo Instrument's TOCG-3041 total organic carbon analyzer. This domestically produced equipment quickly stabilized data and, with reliable detection capabilities, helped companies avoid production line shutdowns caused by water quality issues, recovering tens of millions of yuan in losses. This scene vividly depicts the rise of domestic TOC analyzers.

For a long time, in industries such as pharmaceuticals and semiconductors that have strict water quality requirements, total organic carbon (TOC) analysis equipment has been almost monopolized by imported brands. The prices of three to four hundred thousand yuan and the long after-sales service response cycle have overwhelmed domestic enterprises. The emergence of TOCG-3041 is changing this pattern.

TOCG-3041 adopts dual UV lamp oxidation conductivity method, with a detection range covering 0.1-1500 μ g/L, which can meet the strict requirements of the semiconductor industry for TOC detection in ultrapure water. Its accuracy error of ± 4% and repeatability error of ≤ 2% have reached the international level. The device has passed multiple international and domestic pharmacopoeia standards certifications such as USP<643>, EP 2.2.44, and ChP 2025. In the system suitability verification, the recovery rates of sucrose and 1,4-benzoquinone remain stable between 95% and 105%, which meets the compliance requirements of the pharmaceutical industry.

Previously, when using imported equipment, the annual calibration service fee alone would cost tens of thousands. Now that we have switched to TOCG-3041, not only has the procurement cost been reduced by 50%, but local engineers can also respond to maintenance needs within 24 hours. ”The quality manager of a biopharmaceutical company said so.

In semiconductor manufacturing, the TOC value of ultrapure water must be controlled below 1 ppb, otherwise it may lead to the formation of organic films on the wafer surface, affecting lithography accuracy. The dual UV lamp technology of TOCG-3041 can efficiently decompose trace organic compounds in water, and with high-precision sensors, it achieves real-time monitoring of TOC in ultrapure water.

The application case of a certain semiconductor manufacturer shows that after deploying TOCG-3041 at key nodes after RO membrane and mixed bed, the stability of TOC detection data has increased by 30%, and the equipment failure rate has decreased by 25%. This not only improves the yield of chips, but also effectively reduces production costs.

Compared with imported brands, the significant advantage of TOCG-3041 lies in localized services. Shanghai Botuo Instrument has more than 20 service outlets nationwide, which can provide customers with on-site installation and IQ/OQ/PQ verification services within 48 hours. This is undoubtedly an important support for enterprises that require rapid production.

Once our system suddenly triggered an alarm, and we contacted engineers from Botuo at 2 am. They arrived at the scene within three hours and solved the problem in a timely manner. This kind of response speed, imported brands simply cannot achieve, "sighed the water treatment manager of a certain power plant.

The procurement cost of TOCG-3041 is only half of imported equipment, and its service life can reach more than 5 years. According to the industry average usage cost, a TOCG-3041 can save a company the equivalent of equipment purchase price within three years.

The maintenance cost of this device also has advantages. The replacement cycle for ultraviolet lamps is 5000 hours, and the replacement cycle for peristaltic pump tubes is 1 year. The prices of these consumables are much lower than those of imported brands. Meanwhile, TOCG-3041 adopts a reagent free design, further reducing daily operating costs.

With the deepening implementation of policies such as "Made in China 2025", domestic instruments have ushered in new development opportunities. As a high-tech achievement transformation project in Shanghai, TOCG-3041 not only enjoys tax preferential policies, but also has been included in multiple local government procurement catalogs.

Choosing TOCG-3041 is not only for cost considerations, but also for confidence in domestically produced instruments. I am particularly proud to see our semiconductor production line using 'Chinese chips'. ”A senior executive of a semiconductor company expressed this.

From the laboratory to the production line, from the pharmaceutical factory to the semiconductor workshop, TOCG-3041 is proving with its strength that domestic TOC analyzers have the ability to compete with international brands on the same stage. It is not only a testing device, but also a microcosm of the transformation and upgrading of China's manufacturing industry. In the future, I believe there will be more domestic products like TOCG-3041, achieving breakthroughs and shining in the field of domestic instruments.
