Solid-Phase Extraction Products & Reviews

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.

Bond Elut SPEC is a monolithic sorbent bed manufactured with ultraclean polypropylene plastic and bonded-silica impregnated on a glass fiber disc, resulting in an SPE product that delivers faster sample processing and lower costs. 

Captiva 96-well Collection Plates are specially designed for use with Captiva Filtration Plates, SPEC SPE 96-well Plates and Bond Elut 96-well Plates. The 1 mL capacity provides the volume needed to collect all of your filtrate or eluate. Captiva Pierceable 96-well Silicone Covers are easily applied to completely seal the plates. This ensures no sample loss due to spillage or evaporation, and no sample contamination. The silic…

Filtration is simple, versatile, and necessary to prevent clogging of HPLC columns. Captiva's unique dual depth filtration media provides complete removal of precipitated proteins and outstanding resistance to sample clogging.

Build Outstanding Analytical Performance on a Strong Foundation of Sample Prep

Agilent offers dispersive kits with sorbents and salts supplied in 2 or 15 mL centrifuge tubes to accommodate the aliquot volumes specified by current AOAC and EN methodologies.

Unlike other suppliers of QuEChERS extraction kits, Agilent QuEChERs salts and buffers are pre-packaged in anhydrous packages. This allows you to add them after adding your solvent to the sample, as specified in the QuEChERS methodologies. Extraction Kits include: 50 quantity of 50 mL polypropylene centrifuge tubes with caps MgSO4 and NaCl, or other salts for buffering; pre-weighed in anhydrous packet

The 1290 Infinity III Online SPE system offers automated solid phase extraction (SPE) to enrich analytes, remove matrix components or lower detection limits, for example for trace-level water analysis.

Chem Elut S products enable reproducible SLE results with high data quality and sample capacity. Consistent pore and particle sizes allow for batch-to-batch repeatability and uniform flow. Emulsions are also avoided, because there is no need for shaking. Compared to liquid-liquid extraction, Chem Elut S reduces analyst-to-analyst variability, improves matrix removal, and requires minimal extraction solvent, which leads t…

Advanced Polymer Technology for Simplified SPE   Bond Elut Plexa offers simple, easy-to-use methods with general purpose extraction mechanisms to simplify SPE. In addition, Plexa provides performance enhancements due to a unique polymeric architecture with a non-retentive, hydroxylated, amide-free surface and a non-polar PS/DVB core for retaining small molecules. Binding of proteins and lipids on the polymer surface is minimiz…

Polymeric Cation Exchange for Simplified SPE   Bond Elut Plexa PCX is a further milestone in the development of simple and robust SP methods. Plexa PCX uses a polymeric cation exchange resin that combines the outstanding properties of Bond Elut Plexa - superior flow characteristics and improved analytical performance - with strong cation exchange functionalities. This mixed-mode SPE sorbent removed neutral and acidic interfere…

Pipette Based SPE      Bond Elut OMIX pipette tips reliably purify and enrich femtomole and picomole levels of peptides and proteins prior to MALDI-TOF or LC/MS/MS.
