Identification and optimization of the chemical, series of chemicals or bio-molecule that will interact with the target using impartial, expert opinion about the best equipment, services and the latest techniques
Functional groups, such as octyl (C8) and octadecyl (C18), can be bonded to the silica surface to provide non polar interactions. Each of these sorbents exhibits unique properties of retention and selectivity for a particular analyte. The choice of which sorbent is best for a particular method will be influenced by the percent recovery of analyte from the sample matrix and the cleanliness of the resulting chromatography.

SDB-XC is a poly(styrenedivinylbenzene) copolymer used as a reversed phase sorbent for solid phase extraction. SDB-XC is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked. It does not exhibit the secondary cationic (silanol) interactions and pH limitations common to bonded silica sorbents, so it offers more predictable and reproducible reversed phase interaction.
The Empore™ High Performance Extraction Disk Plate differs in design from plates offered by other manufacturers and requires a specific vacuum manifold. Manifolds supplied by different plate manufacturers are specific to the design of their plates and cannot generally be used with plates from other manufacturers. In some cases, the use of spacers to raise/lower the height of a collection device inside the manifold may overco…
Replacement gaskets are available with the vacuum manifold assembly. The gasket can become worn over time and the seal between the plate and the manifold will be affected. This may result in poor vacuum pressure and negatively effect flow rates. The gasket should be checked regularly and replaced when it becomes worn.
EmporeTM Tape Pads are intended for sealing unused portions of a 96-well solid phase extraction plate during vacuum processing to enable vacuum to be uniformly applied to each well being used. Use a clean sheet each time for maximum sealing ability. Note: these tape sheets are not intended for sealing collection plates prior to sample injection because the adhesive may clog the injection needle.
