PL-SCX is a macroporous PS/DVB matrix with a very hydrophilic coating and strong cation exchange functionality. The manufacturing process is controlled to provide optimum density of strong cation-exchange moieties for analysing, separating, and purifying a wide range of biomolecules from small peptides to large proteins.

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.

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

Filtration is simple, versatile, and necessary to prevent clogging of valuable HPLC columns. Captiva 0,2 μm and 0,45 μm depth filter plates are ideal for filtering samples prior to LC/MS injection. Captiva 10 μm glass fibre filter plates are designed for clarifying highly particle-laden samples, such as freshly thawed plasma and hepatocyte filtration, preventing sample transfer problems from pipette tip clogging. They are perfect for automated systems and for use with DuoSeal 96 96-well seals.

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’.
