Exmere Ltd

Exmere was formed in 1984 for the specific purpose of developing a new generation of silicas for chromatography. The first product was the Exsil 300 range aimed at being an alternative to Vydac. This was followed by the Exsil 100 range which was targeted at Spherisorb. Although a close match, it was found to be slightly less retentive so a higher surface area product was introduced, Exsil 80. This is actually a 90 A media but so was Spherisorb although it was also marketed as an 80A. The high degree on control of pore size ( +/- 3%) allows us to manufacture two ranges which differ only 10A in pore diameter. While deactivated phases were being developed, we were also able to introduce two ranges (Avanti and Avanti BDS) aimed at being alternatives to Hypersil and Hypersil BDS. These are experiencing considerable success in the German market.
