Descrizione: The MetaCarb™ line of carbohydrate columns provides high resolution columns for applications requiring high performance carbohydrate and organic acid analysis. These columns contain sulfonated polystyrene resins in the Calcium (87C), Hydrogen (87H), and Lead (87P) forms, and provide a wide range of selectivities for carbohydrate and organic analysis. They are widely used in the food and beverage industries for analysis of sweeteners, corn and cane sugars, fruit juices, soft drinks, beer and dairy products.

Descrizione: 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.

Descrizione: 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.

Descrizione: 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.

Descrizione: 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.

Descrizione: The Select FAME column is tuned for optimal cis-trans separations of FAMEs, especially C₁₈ isomers.

Fornitore: VARIAN

Descrizione: Bond Elut™ C8 is very similar in properties to C18, but is not as retentive for non-polar compounds, due to its shorter hydrocarbon chain, and therefore reduced carbon loading. C8 is an excellent replacement for C18 when analytes are too strongly retained for effective elution. The potential for polar interactions is somewhat higher than for C18 because there is less coverage of the silica surface. These polar interactions are not, however, a significant property of C8.
