ABOUT GS-TEK
Chromatography experience behind the brand
GS-TEK was founded in Delaware, USA, in 2009 by Dr. Zhenghua “Zack” Ji. Before founding the company, he worked in chromatography column and analytical instrument development at Hewlett-Packard / Agilent. A 2011 interview describes his involvement in the development of capillary GC columns including HP-5ms.
This background helps explain GS-TEK’s technical focus; it does not establish affiliation with Agilent or guarantee that two columns perform identically. Product specifications and method validation remain essential.
