The Grace^® VisionHT^TM Media Platform technology is the basis for a truly seamless column choice.  It is available in 1.5, 3, 5 and 10µm particle sizes in six very different phase chemistries and a multitude of hardware formats, enabling use on any type of LC system.

Grace has been manufacturing silica for over a century and we have been producing sub-2µm media for over a decade - long before the instrumentation was commercially available to use it at its optimum. We produce the base silica, apply the phase chemistry and pack the columns ourselves to provide a reproducible and reliable product. With ISO 9001 certification and full traceability from the base silica to the final column you can rely on us.

You can quickly and easily transfer methods between UHPLC, HPLC and preparative systems to improve laboratory efficiency. Now, you can separate the most complex samples with excellent resolution on any LC system. We use identical base silica and chemistries for all of the particle sizes so that method transfer is simple and straightforward.

Our choice of column hardware is unrivalled. With 1 or 2mm UHPLC formats, Expedite^TM high throughput columns for low volume systems, Rocket^TM columns or conventional Analytical formats for Traditional HPLC instrumentation and 10 or 22mm columns for use on Semi-Prep or Preparative HPLC systems you really can transfer your methods to any platform.

However speed means nothing if you can't get the separation that you need.    The VisionHT^TM media bonding chemistries offer phases that vary greatly in their selectivity.  From a classical high load C18, to highly polar retentive phases, VisionHT^TM Medias give you markedly different separation profiles.  By choosing phases with complementary selectivity, you can run a standard method and have confidence that if one of the phases doesn't produce the separation you need, the other will.  Great results, every time.
