Low Volume SPE Assays Enhanced by Sorbent

Porvair Sciences has announced a range of BioVyonC18 silica columns and microplates for use in low volume Solid Phase Extraction (SPE) assays. 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 immobilizing the C18 sorbent within the porous BioVyon polymer, the company has created a high surface area matrix that provides control of flow rate. The immobilized C18 sorbent cannot form liquid channels and does not require inert frits to support it thereby minimizing hold-up volume.

The product is initially being offered in 96-well microplates as a 10mg per well loading suitable for low volume bioassay preparation and clean-ups.
