"Solid Phase Extraction"

Supplier: Thermo Fisher Scientific

Ideal for the isolation of polar compounds from non polar matrices.

Supplier: Merck

4-Hydroxy-4-methyl-2-pentanone may be used as an internal standard in the analysis of volatile odor-active compounds present in wine using solid phase extraction with gas chromatography (SPE-GC).

Supplier: Merck

AmberChrom™ 1X8 50-100 MESH (CL-) Anion is a strongly basic anion exchange resin which is used as an absorbent in solid phase extraction.

Supplier: VARIAN

Bond Elut™ LMS polymeric sorbent lets you elute without having to add amine modifiers, buffers, or acids. The elimination of secondary interactions means that elution of analytes can be achieved with pure organic solvents or HPLC mobile phase-compatible solvent mixtures of low ionic strength. These characteristics are crucial to allow compatibility with LC/MS or other delicate analytical techniques.

Supplier: GILSON LCMS

This ASPEC® system for positive pressure solid phase extraction (SPE) automation maximises throughput by processing up to four samples in parallel. With its small footprint and multiple probes, it is the ideal choice for reproducible and efficient sample cleanup for clinical, forensic, doping, food, and environmental testing labs.

Supplier: VARIAN

Bond Elut™ PPL is a styrene-divinylvenzene (SDVB) polymer that has been modified with a proprietary non-polar surface. PPL will retain even the most polar classes of analytes, including phenols. The large particle size allows ease of flow for viscous or particulate rich water samples, while the high surface area and strong hydrophobicity ensure reproducible extractions with high recoveries upon elution. Bond Elut™ PPL is suitable for EPA Method 528 ‘Determination of Phenols in Drinking Water by SPE and Capillary GC/MS’.

Supplier: VARIAN

CBA is a mid-polarity sorbent and weak cation exchanger (pKa 4,8). It can be used with a wider range of counter-ions than lower pKa sorbents like SCX and will demonstrate easier elution of quaternary amine functionalised analytes.

Supplier: Merck

Bisphenol E may be used as a reference standard in the determination of bisphenol E in beverages using on-line solid-phase extraction with fast liquid chromatography coupled with tandem mass spectrometry (on-line SPE fast LC-MS/MS).

Supplier: VARIAN

Bond Elut™ PH is a non-polar bonded silica material which exhibits a different selectivity to alkyl or aliphatic functionalised phases such as C8 or cyclohexyl. The electron density present in the aromatic ring affords an enhancement in the retention of conjugated or aromatic ring-containing analytes due to desirable pi-pi interactions.

Supplier: VARIAN

Bond Elut™ C18 OH is a non-end capped version of the octadecyl bonded phases that enables the silanols on the silica surface to be more active. This low-load C18 has well-controlled silanol activity that permits the fractionation of metabolites and enhances retention of basic compounds compared to an endcapped C18. The pore size makes it a good choice for peptide extraction.

Supplier: VARIAN

Solid phase microextraction (SPME) is a technique for extracting analytes from solid, liquid or gaseous samples by adsorbing them onto the SPME fiber and then desorbing them into an inlet, either on a gas chromatograph (GC) or an HPLC system. SPME is amenable to automation using an autosampler or it can be performed manually as well.

Supplier: VARIAN

Florisil is a magnesia-loaded silica gel, extremely polar in nature and ideal for the isolation of polar compounds from non-polar matrices.

Supplier: Whatman products (Cytiva)

The 10 ml UNIFILTER is used with large sample or reagent volumes. Typical applications include biomolecule purification by solid phase extraction and organic synthesis in combinatorial chemistry library generation.

Supplier: Merck

All the individual steps associated with solid phase extraction can be carried out using the LiChrolut® extraction unit. This transparent and vacuum-suitable unit, made of glass, can be used to prepare up to 12 samples simultaneously.

Supplier: Thermo Fisher Scientific

Solid Phase Micro Extraction (SPME) uses a thin-fused silica fiber coated with a sorbent which enables extraction of compounds of interest from liquid or gaseous samples through absorption or adsorption. The fiber is then moved to the injector and the compounds thermally desorbed. The SPME consumables come in two formats SPME fibers and SPME arrows.

The water-wettable, hydroxylated exterior allows excellent flow, even with biological fluids. A gradient of polarity on the polymer surface shunts small analytes to the more hydrophobic centre of the polymer bead, where they are retained prior to the washing and elution steps. Plexa provides these performance enhancements due to a unique polymeric architecture with a non-retentive, hydroxylated, amide-free surface and a non-polar PS/DVB core for retaining small molecules.
