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

The PolarGel range is ideal for use with polar solvents, such as dimethyl formamide (DMF) and dimethyl sulfoxide (DMSO), and for solvent combinations such as tetrahydrofuran with water.

Bond Elut™ EWP is based upon standard particle size silica but with 500 Å pores to allow more efficient extraction of large molecules (>15000 MW), which are typically excluded from standard porosity silica phases.

High efficiency 0,15 and 0,18 mm Int.Ø columns are a simple and cost effective way to increase sample throughput with existing GC or GC/MS instruments.

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™ 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.

The ProSEC 300S column is specifically designed as a single column solution for globular protein analysis. The pore size selection and optimisation provides an extended linear resolving range so that this single column can be used for analysis across the full range of globular proteins.

Supplier: VARIAN

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

Supplier: VARIAN

These columns are ideal for the anion exchange HPLC separations of proteins and deprotected synthetic oligonucleotides under denaturing conditions.
