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.

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.

Bondesil PSA bulk sorbent, 40 µm, 10 g

Supplier: VARIAN

Bond Elut™ LMS polymeric sorbent lets you elute without having to add amine modifiers, buffers, or acids. The elimination of secondary interactions means that elution of analytes can be achieved with pure organic solvents or HPLC mobile phase-compatible solvent mixtures of low ionic strength. These characteristics are crucial to allow compatibility with LC/MS or other delicate analytical techniques.

Supplier: VARIAN

Bond Elut™ NEXUS is an ultra-clean polymeric sorbent which has bi-modal porosity and a high surface area. NEXUS offers a nonpolar retention mechanism with no pre-conditioning required. The large particle size makes NEXUS ideal for extractions from highly viscous samples, such as horse urine.

Based on the same base polymer technology, Bond Elut™ NEXUS WCX is a weak cation exchange sorbent that offers extra selectivity for analytes, such as quaternary ammonium drugs and anabolic steroids.

Supplier: VARIAN

Bond Elut™ PPL is a styrene-divinylvenzene (SDVB) polymer that has been modified with a proprietary non-polar surface. PPL will retain even the most polar classes of analytes, including phenols. The large particle size allows ease of flow for viscous or particulate rich water samples, while the high surface area and strong hydrophobicity ensure reproducible extractions with high recoveries upon elution. Bond Elut™ PPL is suitable for EPA Method 528 ‘Determination of Phenols in Drinking Water by SPE and Capillary GC/MS’.

Supplier: VARIAN

Solid phase microextraction (SPME) is a technique for extracting analytes from solid, liquid or gaseous samples by adsorbing them onto the SPME fiber and then desorbing them into an inlet, either on a gas chromatograph (GC) or an HPLC system. SPME is amenable to automation using an autosampler or it can be performed manually as well.

Supplier: VARIAN

Pursuit XRs are ultra-purity silica based columns designed to increase productivity.

Supplier: VARIAN

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. The unique monolithic sorbent technology used in Bond Elut OMIX consistently outperforms other tips by delivering uniform flow and strong analyte-to-surface interactions. Bond Elut OMIX tips bind more peptides to deliver better sequence coverage.
