About

SeQuant AB was a chromatography company based in Umeå, Sweden, during the years 1987 until 2013. It was founded in 1987 under the name SciTech AB by Professor Knut Irgum at Umeå University and transformed into SeQuant AB in 1997 when new investors entered. The company was acquired by Merck KGaA Darmstadt in February 2008 and renamed to Merck SeQuant AB. Merck used the company as a site for research & development, technology transfer, and a centre for global high performance liquid chromatography (HPLC) support until it finally closed in December 2013. SeQuant AB invented the zwitterionic hydrophilic interaction liquid chromatography (HILIC) HPLC column technology and launched it to the market in 2002 under the name ZIC-HILIC. The company made significant contributions to the rapid popularity increase for the HILIC mode of HPLC by contributing to several highly cited scientific research papers, writing the technology booklet "A Practical Guide to HILIC" which was printed in over 10 000 copies, and arranging close to 30 scientific meetings known as HILIC Day events all around the world. The staff supported numerous chromatographers to successful analyses, for example during the melamine scandal when adulterated milk and foodstuff was intoxicating children in China and other countries.

This website was created by Thom Bizly as a tribute to the spirit of the dedicated people that made all of this possible. Some of these persons can be seen in the photo below, whereas other were not around for this photo session. At the bottom of the page are links to some of the organisations where the former employees of SeQuant AB have continued their careers.
