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.

Supplier: VARIAN

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.

Supplier: VARIAN

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.

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: 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

Bond Elut™ DEA bears some resemblance to Bond Elut™ NH₂ in its properties but with a slightly lower capacity as an anion exchange sorbent. DEA has a moderately non-polar character due to the alkyl side chains on the amino functionality. These groups still afford a medium level of polarity, higher than C₈ but less polar than C₂ or CN-E.

Supplier: Thermo Fisher Scientific
