Solid phase extraction cartridges, Bond Elut™ NH₂

Supplier: VARIAN
Description: Bond Elut™ NH₂ is a weaker anion exchanger than sorbents such as SAX (a quaternary amine sorbent that is always charged) and is therefore a better choice for retention of very strong anions, such as sulfonic acids, which may retain irreversibly on a SAX sorbent. Similar to Diol and SI sorbents, Bond Elut™ NH₂ is excellent for the separation of structural isomers.

Solid phase extraction cartridges, Bond Elut™ SAX

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Bond Elut™ SI

Supplier: VARIAN
Description: Native silica is generally regarded as the most polar SPE sorbent available. Bond Elut™ SI is particularly effective at separating compounds with a very similar structure. Applying the analytes in a non-polar solvent, then increasing the solvent polarity by increasing the concentration of a polar modifier, such as THF or ethyl acetate, delivers effective separations.

Analytical HPLC columns, XBridge™ BEH C8

Supplier: WATERS
Description: The XBridge™ BEH C8 sorbent is less retentive compared to the XBridge™ BEH C18 sorbent. The trifunctionally bonded sorbent offers the widest usable pH range (1 to 12), superior low pH stability and ultra-low column bleed.

Solid phase extraction cartridges, Bond Elut™ C18

Supplier: VARIAN
Description: Bond Elut™ C18 is the most hydrophobic, bonded silica sorbent in the Bond Elut™ range. It is the most popular SPE sorbent because of its extremely retentive nature for non-polar compounds. C18 is generally regarded as having the broadest spectrum of retention among bonded silica sorbents, since it retains most organic analytes from aqueous matrices. When analysing small to intermediate molecules, Bond Elut™ C18 can be used for desalting aqueous matrices prior to ion exchange, as salts pass through the sorbent unretained.

Solid phase extraction cartridges, HyperSep™ Cyano

Supplier: Thermo Fisher Scientific
Description: Solid phase extraction cartridges with medium polarity sorbent, ideal for the isolation of polar compounds from non polar matrices.

Solid phase extraction cartridges, Bond Elut™ CBA

Supplier: VARIAN
Description: 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.

Solid phase extraction cartridges, Oasis® HLB

Supplier: WATERS
Description: Oasis® HLB cartridges contain the Oasis® HLB sorbent, which is a universal polymeric reversed phase sorbent that was developed for the extraction of a wide range of acidic, basic, and neutral compounds from various matrices using a simple, generic protocol.

Solid phase extraction cartridges, HyperSep™ Aminopropyl

Supplier: Thermo Fisher Scientific
Description: A polar sorbent for both polar and anion exchange interactions.

Solid phase extraction cartridges, Bond Elut™ CH

Supplier: VARIAN
Description: Bond Elut™ CH is a mid-polarity sorbent that exhibits unique selectivities for certain analytes. When employed as a non-polar sorbent, CH has the approximate polarity of a C₂ sorbent. Bond Elut™ CH is often a good choice when non-polar sorbents such as C₁₈, C₈ or C₂ do not provide the desired selectivity.

Sentry guard cartridges, XBridge™

Supplier: WATERS
Description: XBridge BEH C18 sorbent can be used over an entire range of mobile phase pH (1 to 12). The trifunctionally bonded C18 ligand provides with a universal column for most HPLC separations and gives you the widest usable pH range, superior low pH stability, and ultra-low column bleed. The XBridge BEH C8 sorbent is less retentive compared to the XBridge BEH C18 sorbent.

Solid phase extraction cartridges, Bond Elut™ PBA

Supplier: VARIAN
Description: PBA is a unique sorbent consisting of a phenylboronic acid covalently linked to a silica gel surface. Covalent processes result in a higher retention to the sorbent surface than other mechanisms, resulting in superior clean-up. The boronate group has a high specificity for cis-diol containing compounds such as catechols, nucleic acids, low molecular weight proteins and carbohydrates.

Solid phase extraction cartridges, Bond Elut™ PSA

Supplier: VARIAN
Description: Bond Elut™ PSA is an alkylated amine sorbent that contains two different amino functionalities, one secondary and one primary. This gives a slightly higher pKa and ionic capacity compared to Bond Elut™ NH₂. The PSA functional group is a very effective bidentate ligand and is therefore an excellent sorbent for chelation applications. PSA has a significantly higher carbon load than most amino functional sorbents and thus is a better choice for polar compounds, which retain too strongly on Bond Elut™ NH₂.
