Alltech Associates Inc. has been an expert in HPLC column chemistry since 1971. Over three decades Alltech grew into a leading supplier of HPLC columns and introduced technologies for both gas and ion chromatography. By the turn of the century, Alltech had become a one-stop-shop for all chromatography needs, including an impressive selection of columns, accessories, and instruments. The marriage of Grace and Alltech, along with Grace’s acquisitions of Vydac, Jones, and MODcol, gave rise to Grace Davison Discovery Sciences – a powerful combination of expertise in silica manufacturing, bonded phase chemistries, and column hardware technologies.
