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.

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™ CN-E

Supplier: VARIAN
Description: 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.

Size exclusion chromatography sorbents, Toyopearl®

Supplier: TOSOH Bioscience
Description: Toyopearl resins can be used in organic solvents or mixtures of organic solvents and water. The compatibility of DMF with Toyopearl also permits the separation of hydrophobic substances such as polystyrenes.

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.

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.

HPLC columns, Purospher® STAR RP-18 endcapped

Supplier: Merck
Description: Fast method development of complex samples across the pH range from 1,5 to 10,5 with different mobile phases and temperature conditions.
Purospher® STAR RP-18 endcapped HPLC columns are designed for universal use. Basic, neutral and metal-chelating compounds can easily be separated with simple mobile phases – naturally without peak tailing. Thanks to its outstanding performance and stability, Purospher® STAR RP-18 endcapped offers maximum flexibility in method development. Robust methods can be developed over the entire pH range from 1,5 to 10,5. High pH-stability allows the separation of strongly basic compounds with alkaline eluents. The combination of high purity silica, best all-round retention characteristics, outstanding pH stability up to pH 10,5, and suitability for up to 100% aqueous mobile phases, make Purospher® STAR RP-18 endcapped an all-round top performance column, almost universal in its range of applications.
