169 Results for: "Solid Phase 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: MACHEREY-NAGEL

CHROMABOND® CN is a cyanopropyl modified silica phase for solid phase extraction.

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.

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: VARIAN

These specialty solid phase extraction cartridges provide higher retention of small organics, including those that are too polar to retain on C18 or polymeric SPE.

Supplier: VARIAN

Bond Elut™ Focus solid phase extraction cartridges with enhanced polar recovery. Features a unique amide functionalised polar-enhanced sorbent technology that delivers outstanding retention for polar and non-polar analytes.

Supplier: VARIAN

Flash cartridges for the purification of organic compounds, and also for scale-up, solid phase extraction.

Supplier: MACHEREY-NAGEL

State-of-the-art spherical polymer for highest demands in solid phase extraction. PS/DVB copolymer with secondary and tertiary ammonium modification for mixed-mode SPE with weak anion exchange and reversed-phase properties (WAX).

Supplier: VARIAN

Bond Elut CN-U is ideally suited for the extraction of polar compounds from a nonpolar matrix, such as hexane or oils. It is suitable for very polar analytes that may be irreversibly retained on SI or Diol (2OH) SPE phases.

Supplier: MACHEREY-NAGEL

CHROMABOND®, Adapters (PVDF) for glass columns (3 and 6 ml)

Supplier: VARIAN

Bond Elut™, Environmental disk manifold

Supplier: VARIAN

Bond Elut™ EWP is based upon standard particle size silica but with 500 Å pores to allow more efficient extraction of large molecules (>15000 MW), which are typically excluded from standard porosity silica phases.

Supplier: Thermo Fisher Scientific

Strong anion exchange sorbent for extraction of weak acids.

Supplier: VARIAN

Bond Elut empty SPE cartridges are made with high purity polypropylene for cleaner extracts.

Supplier: Restek

These glass fiber disks are embedded with C18 or C8 bonded silica. Deep-pore design reduces clogging and allows faster flow rates. Semivolatile organic compounds can be etracted.

Supplier: Thermo Fisher Scientific

A strong cation exchange sorbent for extraction of charged basic compounds.

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

Bond Elut™ SAX is a strong anion exchange sorbent ideally suited for the extraction of compounds such as carboxylic acids, which may not retain effectively on weak anion exchange sorbents. The sorbent is supplied in the chloride counter ion form. You can modify the selectivity of the phase by replacing the chloride ion with other anions, such as acetate and hydroxide.

Supplier: Thermo Fisher Scientific

These columns feature a highly retentive alkyl-bonded phase for non polar to moderately polar compounds.

Supplier: Thermo Fisher Scientific

HyperSep™ C8 cartridges, less retentive alternative to C18 for polar and nonpolar compounds.

Supplier: Thermo Fisher Scientific

A polar sorbent for both polar and anion exchange interactions.

Supplier: VARIAN

Bond Elut™ PCB is a specially designed sorbent which allows for the facile extraction of polychlorinated biphenyl (PCB) compounds from a variety of matrices. Desired analytes can be loaded and eluted using a simple, single solvent method prior to analysis by GC/ECD.

Supplier: VARIAN

A medium polarity sorbent with many uses, Bond Elut™ CN-E is ideal for applications in which extremely non-polar compounds would be irreversibly retained on high carbon load sorbents such as C₈ and C₁₈. This endcapped version of the cyano sorbent is best utilised when extracting analytes from an aqueous matrix.

Supplier: VARIAN

Bond Elut™ Mycotoxin is a novel sorbent which cleans up food extracts for improved trichothecene and zearalenone analysis. Results are comparable or superior to competing methods, including immunoaffinity columns (IaC) and charcoal/alumina columns. The sorbent is a proprietary silica-based ion exchange material.

Supplier: VARIAN

Bond Elut™ C2 is a fairly non-polar sorbent because of the short chain length of the functional group. C2 is often used during the process of method development if analytes are retained too strongly on a C8 or C18 phase. The polarity of C2 is slightly lower than a cyano phase for polar interactions.

Supplier: VARIAN

Clean PP reservoirs contain two PP frits pre-inserted, an ideal configuration for simple filtration.

Supplier: VARIAN
