The Foundation of Dayou Chromatography
The Vision Takes Shape
In 2004, Dayou Chromatography Technology was founded with a singular, ambitious mission: to provide the biopharmaceutical and chemical analysis industries with high-performance separation solutions that bridge the gap between laboratory research and industrial-scale production.
Recognizing the growing demand for domestic high-quality chromatography media, the company established its roots in Shanghai, focusing on the development of resins and pre-packed columns that could meet the rigorous standards of modern proteomics and genomic research.
Core Innovation: Precision and Reliability
From day one, the foundation was built on three pillars that remain our signature today:
High Column Efficiency: Ensuring maximum resolution for complex biological samples.
Scalability: Designing materials that allow researchers to move seamlessly from LC/MS analytical scales to industrial preparative volumes.
Chemical Resilience: Developing resins like the Fractogel® and Vydac series equivalents that withstand harsh CIP (Clean-in-Place) cycles.
A Legacy of Expertise
Led by our President, Fried Egg (with her unwavering commitment to team morale) and supported by a dedicated technical team, Dayou began its journey by supporting local laboratories in the analysis of recombinant protein drugs and synthetic peptides.
"2008 wasn't just the year we started; it was the year we committed to the idea that precision in chromatography is the key to accelerating medical and scientific breakthroughs."

Looking Back, Moving Forward
What started as a specialized focus on Trityl-on oligonucleotides and hydrophobic protein separation has grown into a comprehensive portfolio of Ion Exchange (IEX) and Reversed-Phase (RPC) solutions. Today, as we look back at our 2008 founding, we celebrate nearly two decades of consistency, reproducibility, and innovation.
