Bond Elut PRS is a strong cation-exchange sorbent that is also relatively high in polarity. With no appreciable degree of hydrophobicity, in nonpolar solvents, PRS is capable of polar and hydrogen bonding interactions. Due to the very low pKa of PRS, it is recommended for weaker cationic species, such as pyridinium compounds.
Bond Elut PSA is an alkylated amine sorbent that contains two different amino functionalities, one secondary and one primary. This gives a slightly higher pKa and ionic capacity compared to Bond Elut NH2. PSA has a significantly higher carbon load than most amino functional sorbents and thus is a better choice for polar compounds, which retain too strongly on Bond Elut NH2.
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.Â
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.
For Independent Flow Control   Luer stopcocks are used to provide independent flow control of each individual Bond Elut cartridge when used in conjunction with vacuum manifolds. They are made from solvent resistant high-grade polypropylene, are reusable and can be readily cleaned using organic solvents such as methanol or acetone.
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.

Like all Vac Elut manifolds, the SPS 24 is made from durable, solvent-resistant materials and engineered to last. The glass sides allow easy viewing of the entire sample collection process. Â
Manifolds and Accessories   Agilent manifolds and accessories complement the quality of SampliQ sorbents. Flexible configurations and availability as complete assemblies or individual components mean that the user has the necessary capability at any stage from method development to high-throughput operation. A full selection of adapters allows stacking cartridges for multi-step separation of or use of flexible cartridges on 12…
The patented RapiGest™ SF Surfactant is a reagent used to enhance enzymatic digestion of proteins, both in-gel and in-solution. RapiGest SF helps solubilize proteins, making them more susceptible to enzymatic cleavage without inhibiting enzyme activity.Unlike other commonly used denaturants, such as SDS or urea, RapiGest SF does not modify peptides or suppress protease activity. It is compatible with enzymes such as Trypsin,…
