Separations Products & Reviews

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.

Bond Elut SCX is a strong cation exchanger with a very low pKa. Although the pKa is similar to Bond Elut PRS, the presence of the benzene ring in the functional group increases the potential for nonpolar interactions. This nonpolar characteristic becomes particularly important when conducting ion exchange from aqueous systems, where selectivity towards compounds exhibiting cationic and nonpolar character is seen.

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.

Simplify sodium sulfate mediated drying steps by using cartridges prepacked with ACS grade, granular anhydrous sodium sulfate. Available in three formats (LRC, Bond Elut Jr, and straight barrels).

The same Bondesil sorbent packed into the industry-leading Bond Elut cartridges is available in bulk for large-scale purification or packing custom cartridges. 

Chem Elut is an economical Supported Liquid Extraction choice, available in buffered and unbuffered configurations. Agilent SLE products use a broad-performance inert diatomaceous earth sorbent for rapid, general sample preparation

Empore extraction disks provide a high flow rate solution for large volume sample preparation, and are available in a variety of bonded phases. The Empore disks are available in two diameters, 47 and 90 mm. By increasing the diameter of the disk used, the disk surface area available for sample passage increases, resulting in better solvent flow rates through the disk.

EnvirElut sorbents are specially designed for the extraction of a wide range of compounds from aqueous matrices. EnvirElut herbicides, PAHs, and pesticides are available in standard SPE straight barrel cartridges, which can be used on conventional Vac Elut vacuum manifolds.

Hydromatrix is a high purity, inert diatomaceous earth sorbent available as bulk material, offering end user flexibility and an excellent diversity of applications.

Mega Bond Elut Flash cartridges offer excellent levels of performance and productivity for the purification of organic compounds, but also for scale-up, solid phase extraction. Prepacked, disposable cartridges offer greater convenience than glass columns that must be washed, dried, and repacked after every sample.
