Low volume SPE assays
enhanced by C18 sorbent
Manufacturer: Porvair Sciences
Manufacturer's description: Porvair Sciences Ltd has announced the
availability of a range of BioVyon C18 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
claims to have created a novel, high surface area matrix that provides
excellent control of flow rate. Further, the immobilized C18 sorbent
cannot form liquid channels and does not require inert frits to
support it thereby minimizing hold-up volume. The combination of
these attributes has enabled Porvair to introduce a this range of SPE
columns and microplates designed to provide higher consistency
and greater recoveries for small sample volume assays.
BioVyon C18 is initially being offered in 96-well microplates as a
10 mg per well loading suitable for low-volume bioassay preparation
and clean-ups. In the popular 1 mL cartridge format, BioVyon C18 is
available in a choice of 12.5, 25 and 50 mg loadings to suit individual
applications.
