Porvair Sciences has produced a video that describes the benefits of its range of Biovyon C8 and C18 silica columns and microplates for use in solid phase extraction (SPE) assays.
The video, which is available on Porvair's website, provides an introduction to the Biovyon technology and describes its advantages.
Packed-bed SPE columns and microplates traditionally perform relatively inefficiently when using the shallow sorbent beds necessary to get good recovery from smaller sample volumes.
By immobilising C8 or C18 sorbent within the porous Biovyon polymer - Porvair has created a high surface area matrix that provides good control of flow rate.
The immobilised C8 or C18 sorbent cannot form liquid channels and does not require inert frits to support it thereby minimising hold-up volume.
The combination of these attributes has enabled Porvair to produce SPE columns and microplates that provide higher consistency and greater recoveries, particularly for small sample volume assays.
