    About Exmere

    Four decades of precision silica engineering from the UK

    Exmere Ltd has been at the forefront of HPLC silica development since 1984. As one of the few truly independent silica manufacturers in the world, we design and produce our silica gels and bonded phases entirely in-house at our UK facility.

    Our proprietary manufacturing process gives us the unique ability to independently control particle size and pore size — enabling us to create bespoke products precisely matched to our customers' separation challenges.

    From analytical HPLC to preparative chromatography, from pharmaceutical QC to cutting-edge bioanalysis, Exmere silica is trusted by laboratories and column manufacturers worldwide.

    Our Journey

    1984

    Exmere Limited is incorporated (23 October 1984) to develop a new generation of chromatography silicas; the founder had previously developed the Spherisorb process at UKAEA Harwell.

    First product: Exsil 300 – a wide-pore 300 Å silica; in 1985 the first sub-5 µm wide-pore media on the market.

    Exsil 100 and Exsil 80 – small-pore silicas with pore diameter controlled to ±3 %.

    Exsil ODS-B and Octyl-B – the first base-deactivated analytical reversed phases usable without buffers for many bases.

    Type B and high purity – Exsil Plus, then ultra-pure Exsil Pure.

    Avanti and Avanti BDS – alternatives to Hypersil and Hypersil BDS.

    2004

    First sub-2 µm media and sub-2 µm wide-pore media.
