J.T.Baker® BAKERBOND Speedisk® Hydrophobic DVB, SPE Columns

Supplier: Avantor
Description: These columns feature BAKERBOND® DVB polymer resins, which are the product of ultra-clean polymer microparticle technology. These resin particles have a large surface area, are highly rigid, are stable over pH range 1 to 14, are water-wettable and are not impacted by sorbent drying. These columns are recommended when advanced detection methods are used.

J.T.Baker® BAKERBOND spe™ narc™-1 J.T.Baker® BAKERBOND spe™ narc™-2, SPE Columns

Supplier: Avantor
Description: Standard ultra-clean PP SPE columns are used for samples from 0,2 to 10 ml when standard speed, recovery, and final concentration are needed. These columns are ideal for separating drugs and small molecules. Columns are vacuum packed to preserve sorbent performance. The optimised round-rimmed tube and frits are made from ultra-pure polymers. The tubes fit most processors and racks.

Silylation derivatisation reagents

Supplier: Restek
Description: Silylation is the most widely used derivatisation procedure for sample analysis by GC. In silylation, an active hydrogen is replaced by an alkylsilyl group such as trimethylsilyl (TMS) or tert-butyldimethylsilyl (tert-BDMS). Silyl derivatives are more volatile, less polar, and more thermally stable. As a result, GC separation is improved and detection is enhanced.

Packing material for columns, Res-Sil

Supplier: Restek
Description: These bonded silica packings with n-octane or cyanopropyl (OPN) functional groups yield faster separations of C1 to C4 hydrocarbons, higher thermal stability, shorter conditioning times, and longer lifetimes.

Acylation derivatisation reagents

Supplier: Restek
Description: Acylation reagents offer the same advantage available from silylation reagents: creating less polar, more volatile derivatives. In comparison to silylating reagents, the acylating reagents can more readily target highly polar multifunctional compounds, such as carbohydrates and amino acids. In addition, acylating reagents offer the distinct advantage of introducing electron-capturing groups, thus enhancing detectability during analysis.

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™ 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.
