Welch Materials Inaugurates Advanced Chromatography Production Base in Nanjing

Welch Materials officially inaugurated its new chromatography packing material production base in Nanjing, China on Thursday, January 22, 2026. The grand opening marks a significant expansion of the company’s manufacturing footprint and establishes a new strategic anchor for its global separation and purification business.

The newly commissioned facility is designed to serve as a dual-purpose center for high-end research and development and closed-loop industrial production. By integrating advanced R&D with large-scale manufacturing, the site aims to provide the pharmaceutical, food safety, and environmental sectors with stable, high-performance purification solutions.

“Our new base will be a "key strategic pivot" for the company’s future,” said Tu Bingfang, Chairman of Welch Materials, “we planned the site to produce 190,000 chromatographic columns and 30 tons of purification materials annually, which will surely enhance supply chain autonomy and accelerate the adoption of domestic high-end materials, supporting both domestic growth and global distribution.”

Tao Lei, Deputy Director of the Jiangbei New Area Management Committee, highlighted the project’s role in achieving a manufacturing breakthrough for high-end chromatography packing materials in China, providing critical infrastructure for the biopharmaceutical, food analysis, and environmental monitoring sectors. “The local government will remain committed to supporting Welch Materials’ long-term growth in the region,” he added.

The inauguration also underscored the importance beyond manufacturing. Professor Sun Chunmeng, from the Department of Pharmaceutics at China Pharmaceutical University, expressed optimism that the base would facilitate the translation of advanced chromatographic technologies into high-quality biopharmaceutical applications. “Chromatography materials are the bedrock of drug development and quality control,” noted Sun, “and Welch's new base will serve as a premier platform for industry-academia collaboration.”

Following the ceremony and a guided tour of the production area, the facility hosted a technical symposium titled "New Realms in Chromatography: From Analytical to Purification." The forum gathered industry leaders to discuss the evolving landscape of oligonucleotide quality control and large-scale purification, featuring several in-depth technical presentations:

• Mr. Kong Sudong, General Manager of Suzhou Biosyntech Co., Ltd., delivered a lecture on the analysis of impurity research and quality control in oligonucleotides.
• Mr. Pei Haiyang, Vice Marketing Director of Welch Materials, introduced the company’s latest comprehensive separation and purification solutions.
• Mr. Wang Zhuchao, Senior Applications Manager at Welch Materials, detailed advanced analytical application frameworks.

The launch of the Nanjing production base signifies a comprehensive upgrade to Welch Materials' manufacturing ecosystem. “This investment reflects our long-term commitment to professional excellence and high-quality standards in the global analytical science market,” reiterated Tu.
