Since its establishment in June 2006, Shanghai Tongzhu Chemical Technology Co., Ltd. has always anchored its customers' core needs and closely followed the trend of high-end and intelligent development in the industry. Adhering to the original intention of "improving

efficiency with technology and serving customers with sincerity", Shanghai Tongzhu continues to deepen its product service upgrading. With the continuous increase of market product testing indicators, the company's analytical equipment is also upgrading and improving.

Currently, the company has the ability to test various basic indicators of products such as iron oxide desulfurizer, ET high-efficiency desulfurizer, hydrolysis catalyst, activated carbon, molecular sieve, etc., and has built an integrated full chain service system of

"production testing sales service" for Tongzhu products, injecting strong technical momentum into the high-quality development of the enterprise!

In order to break through the shackles of development and consolidate the foundation of long-term development, the company has strategically laid out the construction of core technological capabilities: forming a special tackling study group and traveling to multiple 

places to learn from advanced laboratory construction experience; Conduct comprehensive research and demonstration, conduct multiple rounds of rigorous comparison and selection of testing equipment, continuously improve laboratory equipment, and achieve a strategic leap 

from "outsourced testing" to "independent and controllable".

The upgrade and update of the laboratory have achieved closed-loop control of the entire process from production to testing and analysis, and deep interpretation of data. Compared to the previous outsourcing testing mode, the testing cycle has been significantly shortened

and efficiency has achieved a qualitative leap; After multiple rounds of authoritative comparison and verification, the consistency of the test results is excellent, meeting the strict quality control requirements of the industry and building a "first line of defense" for 

product quality.

In terms of hardware configuration, the laboratory has strong capabilities: currently, the laboratory is not only equipped with JW-BK100 series specific surface area and pore size analyzers,

 which can accurately complete sample specific surface area and porosity analysis through various physical analysis models, but also equipped with a complete set of basic indicator testing facilities such as carbon tetrachloride adsorption instrument, strength meter, and

 sulfur penetration capacity tester, forming a comprehensive and multi-level product quality testing matrix, providing strong hardware support for quality control.

The deployment of the laboratory has profound significance: it not only provides fast and accurate data support for raw material storage inspection, real-time monitoring of production processes, and final product inspection, but also breaks through the technical bottleneck

 of new product development-helping the R&D team efficiently optimize products, significantly improving product quality stability, and accelerating market demand response speed.

Based on technology, establish an enterprise with quality. The upgrade of Tongzhu Adsorbent Analysis Laboratory marks a crucial step for the company on the path of independent core technology and refined product quality control, laying a solid technical foundation for the 

enterprise to deeply cultivate the industry and serve customers. In the future, Shanghai Tongzhu will continue to drive development with technological innovation, continuously enhance its core competitiveness, provide customers with higher quality and more efficient products 

and services, and embark on a new journey of high-quality development together!
